Atom: the most basic particle of matter
Nucleus: the "heart" of an atom in which the protons and neutrons reside
Electron: has a negative 1 (-1) charge, and moves around in orbitals outside the nucleus
Proton: has a positive 1 (+1) charge, and resides in the nucleus
Neutron: has a neutral (no) charge, and resides in the nucleus
Orbitals: designated areas around the nucleus that an electron is "probably in"
