Protons and Neutrons will give the mass number.

Protons and neutrons make up the nucleus of an atom, which is around by shells of electrons. The atomic number and mass number of an atom can be used to determine how many subatomic particles are present.

The atomic number of an element is the sum of the number of protons in each atom.

Keep in mind:

A certain element's atoms all contain the same number of protons.
Various elements contain different quantities of protons in their atoms.
Protons and electrons are both present in equal amounts in an atom. Atoms have no overall electrical charge since protons and electrons have equal and opposite charges.

Atoms of different elements usually have different mass numbers, but they can be the same
