Isotopes and Elements Practice Problems 

i learn more from this guy than my chem teacher lol thanks dude

This man and the other people who can explain things better than the teacher have a special place in my heart. I’m just a 10th grader in chemistry trying to pass my isotope exam

Why can you be my teacher? The way you explain it make total sense. I really love the way you used visual and hand gesture rather than PowerPoint and audio to solve isotopes and elements problems. So, thank you! Keep up the great work.

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 would give absolutely anything for you to be my private tutor. You teach me more in 6 minutes than my teacher teaches me in 3 hours twice a week. You're literally saving my life.

i am so so happy, i have finished my SSCE without knowing anything in chemistry. but since i started learning from you, i understand everything i did not know. thank you Mr Tyler. you are a blessing to me, God bless you

Thank you for doing these videos. I have been struggling to keep up in my chemistry class and this has brought me up to speed. I sit in class for 2 hours and 50 minutes only to go home and watch these videos! Thank you so much.

You’re a really good teacher . I just wanted to say thank you for posting videos about this kind of stuff because you’re th making me succeed in chemistry. I really hope you start posting more videos.

we have been learning this stuff for weeks and i had no clue what to do in a test and yet this guy has made it crystal clear for me in 6 mins

I've just watched five of your videos and want to thank you and congratulate you on how clearly and how well you explain the structure of atoms. Its really helping to fill in the gaps of my knowledge and understanding. Thanks so much Tyler.

This guy is a legend...his enthusiasm for the hardest science subject..(being chemistry) is awesome...we need more teachers like him

this was so helpful, he can explain things better than my teacher in school. I can finally understand chem better... thank you so much, you really have a special place in my heart.

You're AWESOME! Great teacher...thanks again.

Thank you for helping everyone that is struggling in Chemistry. Trust me I need it! My professor sucks really bad, without you I don't think I would be passing.

This helped me out so much!!!! Thank You dude you're god's gift to the world

Watching videos like this individually instead of working in a classroom makes thngs so much easier because the person explains it so well and im not in a bad learning environment. Also i can learn at my own pace and dont have to stress anyone else out. I can do other things in my own time because i have a life too and if I miss some stuff i can make them up whenever i want

THANK YOU SO MUCH Tyler. You saved me so much money on tutoring. I just wish that half the professors in my school were just as clear as you were.

THANK YOU SO MUCH!! I didn't know how I was supposed to go on my exam on tuesday and this definitely helped. Forever grateful.

I am a chemistry teacher who is working on virtual lessons during the pandemic. Your lesson are done well.

Honestly am short of words am in love with your teaching methods

Thank you so much Tyler. I was just about to drop my chem 51 but then I saw your videos and suddenly ...eureka. Thank you!

This guy right here is a hero in my book. He’s been my saving grace in Chemistry. I’m only passing because of him! Tyler, you’re more than amazing☺️

I have not taken Chemistry in years but I learned this all over again. He has such a passion for Chemistry!

Thank you for producing quality videos! All has helped me so far, can't wait to learn more!

Thank you so much for these videos on ions and isotopes! I was having a hard time with the two, and you helped to clear up all my questions! Thanks again!

Thanks, Tyler! This is such a clear and succinct explanation.

thanks this helped me so much. my teacher is so bad but you made me understand. subbed

Thanks so much for your simple an easy explanation of an atom structure. I surely am going to teach some little novices of science because of your videos. I am sure many students will have clarity because of your clean and right to the point explanations.

Even in the year of 2024 you're helping us so so much!

The best teacher of chemistry ever

Thanks a lot, i get everything from your videos for school, teaching better than my own teacher

You are a life saver, Tyler. Thank you so much!

Best Tutor Ever!

For sodium how come you don’t round the 22 up to a 23?

You are a awesome teacher.A hundred times better than my science teacher.

Thank you for the explanation. Great presentation, very simple and easy

You ROCK!!!!!! I'm so going to watch all your videos!!!!!!

This was done in 2012, very professional, thanks for the help bro

Thank you so much! I had missed this day in class and in needing to study for the chem final, I resorted to RU-vid, and I'm so glad I did because this completely helped me understand the workings of isotopes. Thank you again!

Omg THANK YOU SO MUCH!!! You like explain everything so clearly!! ♥

Good teacher of chemistry you have pedagogic system great job

This was so helpful. Thank you so much!

Nice Job! Excellent You made chemistry easier to understand. Thanks

Periodic Table. Man, not only does this man teach science, he teaches things such as Math in his other videos, I subscribed to him because he is good at teaching.

thank you so much for these videos, you helped me a lot!!!! To understand all my chemistry concepts! Thank youuu!!! You literally explained me this in 6mins my chemistry teacher would take like 2-3 hours still I won’t understand 😭 fr- lol, thankssss!!💖
