There are only two stable subatomic particles, Protons and Neutrons.

Protons: Positive charge, 1amu

The "atomic number" of an element gives the number of protons in its nucleus.

Neutrons: No charge, makes up rest of the atomic mass, 1amu each

The nucleus of every element contains one or more of each kind of stable subatomic particle, except for hydrogen which has ONE proton, but no neutrons
