What term describes the number of protons found in the nucleus of an atom?

Explanation

The atomic number of an element is the number of protons in the nucleus of its atoms, and it determines the element’s identity and its position on the periodic table. For example, every atom with exactly one proton is a hydrogen atom, while every atom with six protons is carbon. Atoms of the same element can have differing numbers of neutrons, forming variants called isotopes, but the number of protons always stays the same.
