What's the atomic number for any atom?

Answer #1

the atomic number is the number of protons found in the nucleus of an atom and therefore identical to the charge number of the nucleus

Answer #2

Atomic number refers to the mass of the nucleus. That number includes both protons AND nuetrons, as both have a similar weight.

Electrons aren’t counted in the atomic mass of a given element. The periodic table would be the best way to find the atomic number of a given element.
