I'm glad he doesn't teach in a way where he assumes that the person watching his video watched all his previous ones before this. I like how he constantly gives an explanation on isotope notation in every video. This is how I get confused in class...when my teacher assumes we learned something in our previous years and we didn't and it's a whole mess because they continue with the lesson based off of basic stuff that we technically should know but we don't.
School is always supposed to build off what you already know, and if you don't know what the teacher is talking about it's your fault, not the teachers. People that blame teachers for their child's mistakes are what destroy the school system because it makes teachers dumb down the material so the most challenged people in a class can understand it and the smarter people don't learn anything.
@@aubreyrogers5264 Your failing assumption is that it could not at all be the teacher's fault. Often times it can be. And they're not even doing that. Teachers don't tell higher level teachers what they have taught their kids, so you can't learn you don't have foundation for. Also it's the teacher's job to cater to their failing students, because the "smarter" kids can wait, and they do learn stuff, they just have to wait. It isn't always about how much a kid studies, but their ability to understand, which isn't made equally. And stop prizing "smarter" kids as better and more worth your time, it's a terrible mentality. My 8th grade teacher had that mentality and my grades dropped. No one is dumbing down anything, the thing is you aren't the only kid in the class.
Hey everyone, I'm here to help. If you have any questions or just want to learn more, click on the link in the description above. It'll take you to a page where you can ask me questions.
You explain this SO much better than my chemistry teacher! EVERYTHING he says goes right over my head. Thank you! And I hope you're doing well nowadays. Almost 11 years now.
Bro, you are the best chem teacher on the internet! My professor is a genius, but not everyone is able to explain that genius as well as you. So thanks, I will tell others about you lol
You are a true genius, Tyler. I grew up watching Carl Sagans' Cosmos series- I was only a child, but I was mesmerised by his charismatic charm and his ability to explain the most difficult concepts in such a way that a young boy like myself could comprehend. I have Aspergers' Syndrome and became a fanatical student of Physics and Astronomy. I would sit with bated breath, pencil and paper in hand, anticipating Dr Sagans' sagacious, engaging and enlightening pronouncements about the mysteries of the Universe. He was the catalyst who served to facilitate my obsession with Science. You remind me of a much younger version of Dr Sagan, with your compelling manner of describing the wonders of Nature and so elegantly employing that universal language of Science- Mathematics. I have written of my most abiding veneration of Dr Sagan elsewhere, and I have no doubt that you are just as inspiring to both younger and older afficionados of Science. You have the potential to be his most worthy successor- the universal teacher of the universal Cosmos.
can't express to you enough how awesome your lectures are! I'm ten years out of high school and relearning these basics for Nuclear Medicine (physician in training). thanks!
you can not imagine how did you benefit me, your way of explaining and the way you talking such a great way that makes us understand easily. So much thanks
You have effectively coached me in passing my Intro class( making a 97) and you may also aide me in my journey to becoming a Nuclear Medicine Technologist. From the bottom of my heart, THANK YOU!!!
You forgot about antineutrino. Antineutrino is emitted during every beta decay, cause when matter is created (electron) an antimatter must also be created (antineutrino) to keep the symmetry. The opposite happens during beta+ decay, (positron and neutrino).
I love the way you teach, I love YOU! I don't know how much I would've had to pay for tutor to explain this to me and not anyone can explain as good as you do. God bless you angel
SAME! my physics teacher really really sucks and no one in the class understands what he rambles on about. this video has helped me sooo much! if it wasn't for my awesome friend who sent me this video, i would sure to fail my exams!
I can't believe he made it 12 years ago and I'm watch his video for my physics lesson now (and the explanation is much more clear than most of teachers in the class)
OMG thank you for this video. I've been banging my head against my desk trying to read and reread my textbook and my professor's notes, but nothing was making sense until I watched this video. Now I get it! Thank for for making it simple!!
So glad that God lead me to your videos. This online Chemistry is trying to take my hair lol. So helpful. Saving my life. 3 more weeks and this Chem is a wrap. Thank you again. Have learned so much in the last 5 weeks of watching your videos
I wasn't sure if I wanted to watch this since it's fairly long but I'm so glad I did. Wonderfully explained in a way even I can understand it. You really helped me to understand this and do some of my homework. Thank you!
Thank you sir! It’s really helpful. I’m actually prepping for the JEE in 2025 and nuclear physics is the topic happening right now. Thank you for helping me clear all the doubts
WOW I'm genuinely lost for words! I love you! WOW WOW WOW WOW WOW!!! I can't put into words how helpful your videos are! THANK GOD YOU EXIST!!! I LOVE YOU AND YOUR VIDEOS!
I got one question here. When a neutron turns into a proton and a beta particle is shot off, this changes the element to a different one, but it is a Positive Ion of that new element (given the Isotope that decayed was electrically neutral). Does this mean, that the newly formed Ion will be looking to then attract an extra electron to cancel off its positive charge or not necessarily? Cheers.
That's a great question. You're totally right that it will now have an imbalance of protons and electrons and will become and ion. However, atoms can gain and lose electrons really quickly and really easily (in most circumstances), so when we write the equation for this kind of decay (and decay in general), we tend not to worry about whether the atom becomes an ion or not, mostly because its charge can change so quickly.
An antineutrino is a anti-matter subatomic particle that is emmited in beta decays. The majority of people doesn't write it down because it is chargeless and it has no influence in the process Hope that's helpful :)
My attempt at explaining why a neutron turns into a proton, a neutron is slightly more massive than a proton due to it's 3rd quark being down not up like in a proton, U-D-D
I know it probably would be too much of nuisance, but maybe you could’ve explained how the W boson interacts with the isotope and when the boson decays, it turns into an electron and anti-electron neutrino. Nonetheless, fantastic video.
Here's my question, though: the neutron turns into a proton and an electron which is ejected from the carbon atom. Wouldn't that leave the resulting nitrogen atom with a positive charge? Because originally, carbon had only 6 electrons, and from what I understand, that doesn't change in B- decay.
Nouri Al-Kadhim I think it's still stable even with a positive charge because its more about the stability of the nucleus rather than the whole atom but don't take my word for it.
sir u did an absolute miracle! before i saw this vid i never did understand any of this but now that i do..all thanks to u..:) i've got a question to ask-do u have any video on radioactivity?
I'm not even in school, but I love these videos. I didn't take Chemistry in school. You see, high school taught subjects in a way that made me despise learning. I thought I hated math and science and chemistry, but as I learned much later, I actually love them. It's just that high school made me think I hated them by the way they taught.
The first 2 minutes of this video already made me understand a lot about Beta Decay. Thank you very much, you explained that really well and so clear. Thank you sooo much. I'm so prepared for my Report about Radioactive Decay now :D
you're my new favourite person! that was so awesome, i spent like the whole afternoon trying to work this out from my sucky class notes. thank you so much :)
Greetings from Denmark: Mystery to me: 14/6 C is the "carbon-14" atom. It has a mixture of 14 elementary particles in its core: 8 neutrons ( which have no electric charge ) and 6 protons p which each has one positive basic charge p+ An electron e has the same amount of charge just negative e- If a basic positive and a basic negative charge collide they will CANCEL each other out. But also if one + and one - are near each other and you are far enough away from the couple , then you will feel no electrical field. Thus at a distance any atom apparently has ZERO electric charge because if there are , say , 6 p+ in the core there will be 6 e- circulating or orbiting closely around the core like planets around the sun. * In CHEMICAL reactions between two materials ( two different atoms ) merely the outer of orbiting electrons are participating in the reaction. The p+ and n in the two cores do not change. Thus actually it is only INDIRECTLY that the number of p+ in the core determines the chemical properties of an atom / material because the number of e- circulating will be identical to the number of p+ because all atoms are electrically neutral otherwise it is a charged ION. * Then a BETA-DECAY takes place. For the 14/6 C ( 8 n and 6 p+ ) it means that an n from the core will disintegrate into two particles: p+ and a beta- Thus the core will change to 7 n and 7 p+ which is a Nitrogen core. The beta- is just another name for an e- which has a very high velocity and therefore FLIES AWAY from the atom 14/6 C or its mutation 7/7 N * The 14/6 C had 6 e- circulating "low speed" around the core. The beta- is NOT one of these 6 e- because the beta- originated from inside the core when the one n "cracked" into a p+ and a fast flying e- ( beta- ) . Thus my QUESTION is: The 6 circulating e- from when 14/6 C still existed ARE STILL THERE and so to speak "wave goodbye" to the beta- flying away. Thus we have an 7/7 N core with merely 6 e- orbiting That is not an 7/7 N atom but a positive charged 7/7 N+ ion. If this 7/7 N+ ion wants to become an 7/7 N atom it will have to react chemically with some other material ? ?
+dreo149 I think it is the fact that he has a little bit of empathy for us learning it. Most chem teachers teach in a very annoyed condescending tone like we are morons for not already knowing this stuff. Tyler makes me feel like I CAN learn it... not that I SHOULD already know it.
You have explained this amazingly well! Thank you! I was having trouble finding something that explained it easily, and you've done just that! Keep up the amazing work! (I'm going to recommend this to my teacher)
WE ALL LOVE YOU THANK YOU FROM THE BOTTOM OF OUR HEARTS you are so talented in the way you carry out explanations and can make rocket science understandable
BETA Plus DECAY and My Model for PROTON and NEUTRON BETA PLUS DECAY: When energy is added to an unstable NUCLEAS , a PROTON and ELECTRON combine to build a NEUTRON. Then it releases a POSITRON and NEUTRINO. BUT where did the POSITRON come from? No one seems to know. This model may explain it, while fitting into my larger model outlined elsewhere. BACKGROUND of MY MODEL Proton = two positrons and one electron. Charge +1. Neutron = one proton plus an added electron. Charge 0. BETA PLUS DECAY: see drawing. Start with an unstable PROTON Then add ENERGY from virtual particles containing both an electron and positron. The ELECTRON combines with the PROTON TO make a NEUTRON. The remaining POSITRON is released with a neutrino. This works in reverse for an unstable NEUTRON in BETA MINUS DECAY. This answers where the missing positron comes from in beta plus decay. This answers why a neutron breaks down into a proton and electron. This explains electron capture, where an electron and proton make a neutron.
i hope you keep post these kind of helpful video.!!!!!!! i like how you do a lot of example problems and how you explain stuff. Thank you so much this video helped me a lot. God bless you.
Short, Sweet and effective.... God bless you! I have one question, in IGCSE physics book, there is something called "antineutrino"... Would you plz explin about that as well?
I get the concept, but have a question. As we saw in Carbon, when the difference between the atomic mass and the atomic number is 2, Beta decay takes place and makes a stable Nitrogen element. But, what if the difference is more than 2, let's say 18, as is seen in some of the larger elements. What would the total process look like then? Thanks for the awesome video.
I'd like to meet you someday and say thank you personally.💗 It seems impossible though but I hope so. You really help me to learn these things that my professor failed to do. Thank you a lot. God bless.
In Beta decay when extra electron is produced as beta particle then is there Change in atomic charge ???the atom would not remain happy as it would gain a positive charge. please answer this question quickly it's a very kind request
[QUESTION] Really thanks bro, you helped me a lot. I'm gonna continue and watch about Beta Positron, but I got one more question here. Why actually would an element want to undergo Beta Decay. I know you have already told that, but in my textbooks I found one more thing contrary to the thing you said. I usually follow up Halliday, Resnick Walker- Fundamentals of Physics, and SL Arora - Physics Simplified (A book available in the Indian subcontinent- South Asia), in that it is written that all elements with more atomic number usually have more neutrons to balance out the proton-proton repulsion (aka coulombic repulsion) and that's how they make themselves more stable. So if more neutrons are present to balance out the proton repulsion, then why would a neutron wanna undergo Beta decay and form a proton knowing that it'd only increase the repulsion? Also, in nuclidic chart(Segre Chart) too, all stable elements with low atomic number tend to lie in a straight line which states that an element is most stable when no. of protons = no. of neutrons, then why would they want to undergo decay? Sorry for the trouble, and thanks in advance.
The reason for beta decay is to become more stable. In the nucleus there are two forces, the proton-proton repulsion as you said, and strong nuclear force which hold the particles together. When these two forces are balanced, the atom is stable, therefore no decay occurs. But when we get things like isotopes, where there are more or less neutrons but the same amount of protons, this balance of forces is unbalanced, therefore the atom is unstable. A neutron would want to become a proton because there is too much strong nuclear force and not enough proton-proton repulsion. Basically, beta decay occurs in isotopes.
Axel Mann I don't disagree with the core message of your comment, but implying all isotopes are unstable is incorrect. All versions of an atom are isotopes, including those with an exact division between neutrons and protons. What you're thinking about are unstable isotopes.
For the second problem you don't have to write out the balancing. An easier way is to just do 32+0= 32 for the Atomic Mass and 16+-1=15 for the Atomic Number.
You know I don't really understand what my chemistry teacher say but I really like your explanation that I can easily grasp the idea. I sincerely appreciate your work and thank you so much. By the way, I can't find the the video of gamma decay??? Also I don't know why the above link, vespr.org....doesn't work? Kindly please advise.
This has been of great use. Actually I've watched both of your videos on both alpha and beta decay. But I still wonder what should I consider to know that it will undergo a beta or alpha Decay?
Just a question that drives me crazy: Right after the beta decay happens to the 14C that turns in to 14N... ...the logical consequence is that the 14N must become "+1" positive charged, because the beta particle is emitted and there are no additional electrons that e.g. initiated the beta decay(as I know it's a sponatneous reaction). Why is this not notated anywhere?
