Atomic Number (Z)
The number of protons in the nucleus of an atom. It defines the identity of the element.
Z = 1
Mass Number (A)
The total number of protons and neutrons in the nucleus.
A = 1
Isotopes
Atoms of the same element with the same number of protons but different number of neutrons.
Isotopes of Hydrogen will always have 1 protons.
