Proton:subatomic particle, symbol p or p+, with a positive electric charge of 1 elementary charge and mass slightly less than that of a neutron
Neutron:the particles in an atom that have a neutral charge. They aren't positive like protons. They aren't negative
Electron:the negatively charged particles of atom
Atomic Number: the number of protons found in the nucleus of an atom of that element, and therefore identical to the charge number of the nucleus
Atomic Mass:the mass of an atomic particle, sub‑atomic particle, or molecule
Valence Electron:an electron that is associated with an atom, and that can participate in the formation of a chemical bond
