| Binary Compound | A chemical compound composed of two elements |
| Chemical Bond | The force that holds together the atoms in a compound |
| Chemical Formula | A precise statement of the elements in a compound and their ratio |
| Chemically Stable | An atom whose outermost energy level is filled with electrons, so that it does not form compounds under normal conditions |
| Covalent Bond | A type of chemical bond formed by atoms when they share electrons |
| Hydrate | A compound that has water molecules chemically attached to its ions |
| Ion | An atom having an electrical charge, either positive or negative |
| Ionic Bond | A type of chemical bond that holds together compounds of oppositely charged ions |
| Nonpolar Molecule | A molecule in which the atoms have an equal attraction for electrons, so the molecule is not polarized into positive and negative ends |
| Oxidation Number | A positive or negative number that indicates an element's ability to form a compound |
| Polyatomic Ion | A group of covalently bonded atoms in which the whole group has a positive or negative charge |
| Polar Molecule | A molecule in which one atom has a stronger attraction for electrons than the other, giving the molecule a positive end and a negative end |
