I'm a chemistry teacher... Your explanation is far more better than what I was taught and what I've been teaching my students... I learned!!

No lie bro you nailed it with your explanation in videos like these. This talent is yours and God knows you make life for others a lot easier

I love how to talk at a good pace! Your videos are so much better then crash course, he talks so fast I can't process what I'm hearing.

Throw Back when I has chemistry in high school and this guy taught me more than my teacher ever did

Tyler! Tyler! Tyler...I'm 45 yrs old and going back to vocational school. Started reading my books and overwhelmed even while reminding myself it's the first read of many before I start to absorb information. I never even took Biology and here I am in Anatomy/Physiology at once. Thank you for your videos. Your gift of teaching is so appreciated. Who would of thought how much we can learn through this "internet" stuff. Thanks again! :-)

whos teacher send u here in 2020 bc of zoom smh

My teacher made us look this up 😒😒 but good video i like how you explain everything👍

when your teacher sends you to watch a 10 min vid smh

Back in my day: "Wow, you are such a good teacher. You teach all the things so elegantly. I love your teaching methods." Couple years later: "I am here because tomorrow's my chemistry exam. And this is helping me so much. Thank you" Today: "My teacher sent me here because zoom, online" (And shaking their head for some reason)

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.

I think every teacher should give an introduction like trivia, history, etc to almost any subjects before the class begin. Just like what you said about Democritus, somehow it pumped me up a little bit more, to learn and to appreciate science.

Dude my chemistry teacher made me watch this when he was gone and had a sub, and it was genuinely one of the first videos that was science related that I could focus on and get work done, and I may even watch some of ur videos in the background while I work on other stuff

I actually hope you're having the best day ever and that your life is going amazingly because you literally saved mine almost a whole decade in advance when you posted this

OMG! I really have no idea how I passed chemistry before these divine videos were made !!

aye thx for helping me fill out 70% of my chem hw

Your videos are always so organized and creative. Thank you so much, I have truly learned alot .

literally this channel is the only helpful and understandable one for me when I'm learning chem

this is great! i actually understood this well

thank you so much for this video

Amazing videos, I learned too much things from your videos. You teach us in acreatie way, I feel like I couldn't understand anything in chemistry except after using your drawings and your awesome way of teaching. Thank you again and I have a request on videos about the " Energy Levels, and Sublevels in Atoms " and " Electron Orbit and Atomic Orbitals " and what contain the other, because I really got confused with those 4 terms

Best explanation of the atomic models I’ve seen so far! Great content!

omg! i just got it.. read my book like.. a 100 times and still couldn't get it caz , its hard to understand when u cant picture what they are trying to say! but u dd a great job with the whole thing!! i have a test tmr and THANK YOU!

Tyler Dewitt, you are the best. I never met or heard anyone who would explain the complicated enough things so logically, clearly and entertaining. I wish somebody thought me chemistry/physics like that earlier. But better later than never. Great job! Thank you.

I vaguely remember... some of these concepts... The Bohr model was used in the classes I took to explain atoms, except I've been led to believe that's how atoms work and this is the first time I've seen orbitals at all (at least, I *think*... the material was difficult enough to learn already, even if I _did_ have an awesome science teacher). So thanks for clearing that up for me, like, ten years later. :P Will happily watch the rest of this series.

Love your videos, don’t love how you use the word “lying” at the end, only in the context of recent trending spike of antagonism against science, especially online/on this platform especially. You’re not lying, you’re simplifying for the purpose of understanding, which is utterly acceptable, and I appreciate, because an understanding of chemistry never came to me as easily as an understanding of other sciences. On another note, your explanation of the schrodinger model has left me with a lot of questions, in particular regarding absolute states of electrons when charged by photons (I came here from a series of videos trying to explain spectroscopy, in case that gives some context), but I evidently need to watch a little more before knowing the right questions to ask about either subject. Do you have a website that best describes which order to watch your videos? Is it just the order you uploaded them on RU-vid? I’m starting to watch your playlists, but they seem to go back and forth in terms of level of understanding

For my presentation tomorrow! Thanks Tyler!

I love the way you explain. It's at a moderate pace and the diagrams and written information is so helpful while learning. Thank you for spending your time on doing this!! This has helped me so much!!

I never knew that electrons buzzed around the atom like how you explained in the Quantum Mechanic Model! Very good explanation of how the electrons worked!

Great video. But one fact i wish you included in the video is that according to Quantum mechanics theory of atomic model , The electrons are not buzzing around like flies drawing those shapes, instead they are more like wave form and have an area of probability where the electron lies. when disturbed the electrons behaves like a particle , when undisturbed electrons behaves like a wave . That dual form of electron is what created curiosity and pushed scientists to experiment and think about adopting atomic model based on quantum mechanics theory which accommodates wave form . PS : this is my understanding about atomic model by reading articles and watching many videos.

U made our subjects easy , up to some extent!😊 Thank u!

You're literally the best teacher ever!

I've used the Bohr model a lot in chemistry.

We got told to write out the timeline of atoms, my teacher gave us videos but it wasn't very helpful... But then I found this video, I love how you explain things and this was very helpful! :D

this is the 6th video I watched about atoms history and this is totally the best one.

Trust me watching this at 1.25 speed works a lot. It feels pretty regular and time went flying

In love with his videos.. precise teaching and c'mon - I can't be the only one watching his videos right before a test

One of the best demonstratons I have ever seen

I Learned so much from your videos. I knew nothing regarding gas laws and it's formulas but I watched your videos and felt comfortable hours later taking the test!! Thank you for your videos...I learned so much within the short time I watched the videos than the three weeks in lecture! Sadly, I cannot access the website! Thanks again so much!

I left my book in school for the summer holidays so this really helped me with my homework Thanks

thank God for this man. I spent 45 min trying to understand my first lecture of chemistry at uni and was definitely not interested and did not understand what my teacher was saying. In less than 15 min, he nailed it and I understood.

I like the way you speak and explain the complex things in easiest way....

I am so thankful for your videos, they are excellent! However, I have a request on a video about the equilibrium concept, as this is something I (as well as several others in my class) find difficult, and none of our teachers have so far been able to give us a good definition!

This channel is pure golden nuggets! Very clear, step-by-step and visual way of explanation ! Awesome !

anyone can learn chemistry very easily by these videos ... I want to say only that thank you SIR..

amazing presentation it helps a lot thank you sooooo much

This is my absolute favouite video on RU-vid. Thank you for a stunning explanation.

your videos are amazing dude!!!

internet is a gr8 blessing coz of few teachers lyk u! in love wid ur video...

Dude awesome videos! Very well presented! Keep it going

This lecture is awesome! Thank you so much, I now understand the difference between The Bohr and Quantum models :)

You saved my butt.

Just Awesome explanation. Watched & Subscribed.

Wow, my teacher gave us an assignment for different structure of atoms and the only place where I truely understand is a 7 year old video. This is just amazing, great video 👏👏

Thank you so much! You've made this sound so simple yet very informative!

could you possibly go over the law(s) of: Definite Composition, Conservation of mass, and multiple proportions?

Me: Watching the video being bored Ad: I HAVE A CHALLENGE FOR YOU Me: gets scared cause of how loud it is while having headphones in

You're seriously the best. Thank you for the videos. I wish there were more teachers like you

keep making more please and thank you

Fantastic Tyler..great insights. and protocol (videos)

The bit you said it sounds like Captain Planet made me laugh 🤣

You are life saver for my 13 year-old daughter. You made the hard to understand concept so easy! Thank you!

I liked how u summarized the HISTORY of the atom

This is great! I actually understood well. Appreciate you efforts. Keep going.

this really helped a lot, thanks :3

this whiteboard thing you've got going on is genius. i watched all the VESPR videos. your style makes it easy. i'm going to stick around and soak up everything else

Thank you for this video, I've been searching a good explanation of orbitals and I just wasn't able to find It until now.

How excellent description of you THANK YOU SO MUCH This video can help me a lot (Y)

Could you make a video about the s, p, d, and f orbitals, please? Thank you do much for your videos!

I do love how visual this video was.

Love the way you explain! I always use your videos as topic introduction. Thanks!

Tysm it’s currently 11:00 and cramming for my chem test!!! 😭

Sir love from India and your diagramatic explanation is fsr better than Animation sir you are literally so good at teaching I wish to god that I can meet you someday 🎉🎉🎉

Thank you for explaining the concept well! The many different kinds of atom models are very fascinating and helpful to know. The topic now makes more sense to me thanks to you. This refreshed my mind about the different models of atoms.

You are the best teacher

Such a great video tyler. You taught me more in 10 min then my science teacher has all year! Very good job man keep it up!!

It’s J.J. Thomson (no p) Great video!

Thank you so much sir ! It's the greatest explanation for atomic structures on RU-vid.

I love your videos so much they're incredibly helpful and have saved me

Thank you so much. I love your videos, you're just so talented at explaining things :)

Tbh Aristotle seemed like a crazy maniac ...he even actually believed the theory of spontaneous generation of life..

Digging the Captain Planet mention!!

You are truly the best chemistry teacher... Plz make more videos

I gotta appreciate you sir for your hardwork and dedication

one word- A GREAT TEACHER

tnx for this video... i am now ready to take the exam!!! 😀😀😀

I would like to correct the spelling of J.J. Thomson's name. There is no p.

U r highly creative and makes complicated things into simple fragments!! :)

Hey Tyler actually the electrons are revolving according to the Rutherfords model of an atom. And it was discarded because a charged particle undergoing circular motion would accelerate and an accelerating particle looses energy. Hence, the electron would fall into the nucleus and the atom will collapse. BUT this does not happen. And you did not mention any of that stuff in YOUR VIDEO!!! IF I AM NOT WRONG !*#@##!!

Excellent way to make understanding of the concept in a very clear method.👍Kindly also post bohr's model and its applications..

very helpful video for my atomic theory timeline homework

I am fan of your wonderful videos. I am a teacher in Physics and with those videos you shared via youtube I am now very confident of the concepts and principles for each topic I'll be teaching in my class. Thank you and may the Lord always blesses you with good health especially to your endeavour.

You can add a bit of background music so it is soothing for the brain while understanding the topic that you are teaching.

I wish you could "lie to us a little" in Hebrew. In the meantime I'll continue to translate. please keep up the great work.

Life makes sense when you speak, great teacher, thanks so so much for your contribution

Dalton's Model of the Atom (1808) maybe he described the building blocks of the Quarks, Leptons,... ?

Your a wonderful teacher. Do you have any video feeds for determining acid and bases pH, pOH, [OH-], [H3O+], concentration and dilution calculations, and stoichiometry applications?

do you have videos on quantum numbers?

You are the best, Tyler!

scientists before 1940s: you can't split atoms! Oppenheimer: hold my beer
