Question

Aside from neutrons, what else is found in the nucleus of an atom?

Answer 1

Well, the nucleus also contains protons.......

Explanation:

Well, the nucleus also contains protons, which are massive nuclear particles each with a formal positive charge. And the number of protons gives `Z`, the atomic number, which number determines the identity of the element: `Z=1, H`; `Z=2, He`;..........`Z=6, C`;....`Z=33, As`;.....

In the neutral atom, why is the number of electrons equal to the atomic number?
