Nuclide Symbols: Atomic Number, Mass Number, Ions, and Isotopes

How do we represent an atom, with all of its protons, neutrons, and electrons? With nuclide symbols, of course! These show the type of element, as well as the atomic number, mass number, and electrical charge of an atom. That's all you need to know!

Check out "Is This Wi-Fi Organic?", my book on disarming pseudoscience!

My teacher could never explain this as clearly as you. Thanks Dave

I'm a chemistry teacher. Your use of graphics and your clear explanations are magical. Thank you!

I’m binge watching the entire series because I have a final test tomorrow. Thanks for such great review

[gandmsparklydaynight]

Impressive you explain better than my chemistry teacher!!

[damienkern]

Bless YouTube educators. Poor kids would be lost without them

[satyamchand]

Blew my mind at first but after giving some time to this video, it proved to be very effective and useful.
Thank you very much.

This guy is the GOAT!!! My mom asked me if I needed tuition for Chemistry:
ME: I pull out my phone, swipe to youtube and show her Professor Dave :)

[unknownguy]

It's shockingly short and very well explained. Thanks Professer Dave

and in a single evening you’ve summed up my semester of chemistry except now i can actually understand it. life is magical

[amandapager]

Thank you so much for this, my comprehensive test is a day after right now. I’m studying for 12 hours and this helped me so much. Thank you

[balakumaran]

most powerful thing of your teaching style is let's check comprehension. comprehension makes concept as strong, thank you professor

[TheToxicMegacolon]

My first chemistry prof, thank you so much!

[manyboy]

thx i usally don't comment on Videos but this helped me for my test so thx

[ceylon]

Thank you so much! This really helped me better understand the charges with electrons/protons on the nuclide

I'm taking Prep General Chemistry this summer in a 4/5 week college class so in Fall I can take General Chem. I haven't done chemistry or math since HS and I was so scared but these videos are helping a ton! I actually didn't learn how to calculate all these things because we didn't have a chem teacher until like MARCH so we had to scrunch everything and really only learned about the periodic table and different types of mixtures.

I'm in year 8 and I want to study more complex things than what I am taking now, this was really helpful thanks.

Cover more topics, we're waiting, you are literally the smartest man in existence.💖

[xBobz]

Very concise summary of periodic table basics!

[roce]

your the best. I am starting to hate chemistry but you made it simple. thank you

[chomaythan]

Thanks a lot. I am a visual learner. I really want to learn chemistry but textbooks are a bit complicated for me. It is also because I am not a native English speaker or learner. I do not need to spend one-hour reading textbook to understand. Your videos explain the simplest way to understand chemistry in such a short time. Thanks a lot Prof Dave.
