|---|---|
| chemical bonding | the combining of an atom to form molecules or ionic compounds |

| valence electron | electron that is found in the outer most shell of an atom and that determines the atom's chemical properties |
| ionic bond | the bond that forms when electrons are transfered from one atom to another which results in a positive ion and a negative ion |
| ion | charged particle that forms when an atom or group of atoms gains or loses one or more electrons |
| crystal lattice | regular pattern inn which a crystal is arranged |
| covelant bond bond formed when atoms share one or more pairs of electrons | bond formed when atoms share one or more pairs of electrons |
| molecule | the smallest unit of a substance that keeps all of the physical and chemical properties of that substance |
| metallic bond | bond formed by the attraction between positively charged metal ions and the electrons around them |
