Chemistry

Atoms are composed of a nucleus containing protons and neutrons, surrounded by an electron cloud. The proton count defines the atomic number, crucial for identifying elements. Neutrons contribute to the mass but vary in number, resulting in isotopes when they differ while protons remain consistent.

Determines if an element is an isotope or not

It is NOT an isotope if the protons, ALONE, are not the same.

Is an isotope if the mass of protons and neutrons are the same. Also is a proton if protons are the same and neutrons are not.
