What never changes in a element's atom no matter what? hint: it's what's used to identify the element on the periodic 표, 테이블 and each element has a different number

and 당신 take the cup....yay!! woohoo! yay....

I'm a nerd! Yay! :D

Of course it never changes, every element has a different amount of protons in its nucleus, it's what identifies it, the amount of neutrons and electrons can change, which leads to isotopes (different neutrons) and ions (different electrons)

Ions, that's what they're called. Couldn't remember, we went over this a while ago...
