You can tell the identity of an element by knowing the # of protons found in the nucleus. This number is known as the "ATOMIC NUMBER." This number also represents the number of electrons found outside the nucleus of a neutral atom.
In addition, you can tell an elements "ATOMIC MASS NUMBER" by knowing the number of protons (atomic number) and neutrons found in the nucleus.
Atomic Mass = Atomic Number + Neutrons = Protons + Neutrons = Electrons + Neutrons
