I've had university chemistry, it was hard to understand, you teach it the best I've experienced. I watch most of your videos on math , very nice . Thank you, I'll be waiting and watching in the future , thank you.
does the periodicity of the elemtns change when temperature and pressure conditions change, e.g. extremities like plasma instead of gas and superconductivity close zero Kelvin?
@1:03 Hey Mac - get it right because you are a teacher, right? No, not all the elements on the periodic table are found in the human body. The human body is made up of *21 elements* from the 118 elements on Earth. These elements combine to form the molecules that make up DNA, cells, tissues, and organs. Now, go back to your studies - good boy!

Best teacher ever.

Agreed, I like how thorough he is, as well as how simple he is
I studied Chemistry many years ago and was not good at it. Amazingly watching these video made the subject so clear. Thank YOU!!!
I love this guy fr it’s been a breeze learning from him daily.
Best teacher ever. Best teacher ever. Best teacher ever.
Best teacher ❤❤🎉🎉
Amzing lesson. Thank you
Excellant sir, i love you
Nice 👍
Very nice indeed ! 😊
Yeah I love it❤
Great !
THANKS AGAIN... SIR...!!!

What parameters do determine the similarity of properties of the elements in the same column (how is a "group" specified)?
are matalloids the same as semiconductors?
are the "noble elements" the same as insulators?
what are the common similar properties of the third column: of lanthanide and actanide?

How come you were able to explain this in less than an hour, where my professor had trouble over a 3 month period?

💀💀💀
I have periodic table yeah
First
I want to be a footballer but my dad doesn't believe me mu mom does tho
