| Atom | All things are made up of atoms, composed of protons, neutrons and electrons. Actual weight 1.66x10(-24) grams. |
| Atomic Number | number of protons in the nucleus of an atom |
| Atom Nucleus | made up of protons and neutrons, holds the weight of the atom |
| Atomic Weight | number of protons and neutrons in the nucleus of an atom, * atomic weights are averages. |
| Electron | negatively charged subatomic particle found in the shell of an atom, has no weight |
| Electron Shell | The energy level of an atom, all atoms have at least 1 and a max of 7. Each shell holds a minimum of 1 electron and a max of 32, depending on its level K thru Q. Shells are added to keep balance..equal protons and neutrons. |
| Electron Shell Maximum numbers | K-2, L-8, m-18, n-32, o-32, p-18, q-2 |
| Elements | 92 naturally occurring elements, all others are man made |
| Neutron | Positively charged, subatomic particle, fond in the nucleus of an atom, with a weight of 1. |
| Protron | Nuteraly charged subatomic partical found in the neuclueus of an atom with a weight of 1. |
