well.. the atomic number for the nucleus is the number of protons inside of it.

The Atomic Number is based on the number of protons, positively charged subatomic particles, in a nucleus of an atom. Hydrogen, the smallest atom has one proton so its Atomic Number is one. Carbon has six protons so its Atomic Number is six and so on.
Also in the nucleus are neutrons which have no charge and are there mainly to add mass to a nucleus. The more electrons an atom has buzzing around the nucleus, the more mass it needs to hang on to those frisky negatively charged orbitors.

Hi,
It depends on which nucleus you're talking about. Different elements have different numbers of protons, and neutrons in their nuclei, which is what the atomic number is based on.
Hope that helps,
Matt

the nucleus is the atomic mass subtract the atomic number(protons) that is the number of neutrons
