0:42 You can have different Versions of the same Element
Isotopes= Different Versions of an element
1:09 CL-35 has 17 protons and 18 neutrons
2:08

Khan academy is best

[@vyomyadav6497]

You really are a great teacher I would just say that there is an Indian Scholarship exam KVPY, I ll hope you do some research and and make a general video on main topics included in kvpy in all physics, chemistry and maths.

I do not know where u got the percentages of each chlorine but sure

[@wiggumesquilax9480]

In nature, 75.77% of chlorine found is chlorine 35.
What is meant by the term "in nature"? Samples of chlorine found on Earth, estimations of chlorine in the universe, something else?

[@rwayle]

it’s from samples from all around earth, they are all roughly the same (give or take a decimal place here or there)
