The number of protons in the nucleus of an electrically neutral atom is equal to:

a) the number of electrons in the nucleus.
b) the number of neutrons surrounding the nucleus.
c)the number of electrons surrounding the nucleus.
d)the number of neutrons in the nucleus.
e)None of the other choices is correct.

I know that for it to be neutral it has to be the same number of electrons than protons, they cancell each othe out, but I'm am not sure if it is the ones surrounding it or in the nucleus.

a or c?? and why?

Thanks!

Are electrons found in the nucleus ?
