We can find Atomic Mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.

83.98 amu is the Atomic Mass, 36 is the atomic number.

The atomic number is the number of a chemical element in the periodic table of Mendeleev; the atomic number is equal to the number of protons and electrons.

The atomic mass is the mass of an atom expressed in relative atomic mass units.

atomic number = number of protons = number of electrons

atomic mass = mass of protons + mass of neutrons
