| chemical bonding | the combining of atoms to form molecules or ionic compounds |
| chemical bond | an interaction that holds atoms or ions together |
| valence electron | an electron that is found in the outermost shell of an atom |
| theory | an explanation for some phenomenon that is based on observation, experimentation, and reasoning |

| ion | a charged particle that forms when an atom or group of atoms gains or loses one or more electrons |
| crystal lattice | a three-dimensional pattern in which a crystal is arranged |
| covalent bond | a bond formed when atoms share one or more electrons |
| molecule | the smallest unit of a substance that keeps all of the physical and chemical properties of that substance |
| metallic bond | a bond formed by the attraction between positively charged metal ions and the electrons around them |
| diatomic molecules | molecules made up of two atoms |
| malleability | the ability to be hammered into sheets |
| ductility | the ability to be drawn into wires |
