| A | B |
| transition | metals in Groups 3-12 that can form 2 or more ions |
| polyatomic | ion contained in parentheses if more than one is used in formula |
| electroneutrality | positive charges must equal negative charges |
| ion | can be positive or negative |
| ionic bond | forms between ions of opposite charge |
| oxyanions | end in -ite or -ate |
| anhydrous | what is fomed when a hydrate is heated & water is removed |
| formula unit | simplest ratio of ions in a crystal |
| electronegativity | what determines if covalent bonds are polar or nonpolar |
| intermolecular | forces that are weaker than bonds |
| covalent bond | forms when atoms share electrons |
| chemical bond | forms due to attraction of nuclei for electrons |
| valence | electron shell that wants to be filled with 8 electrons |
| metallic bond | forms when electrons flow in the conduction zone or sea of electrons |
| double bond | forms when 2 pr of electrons are shared |
| london forces | very weak instantaneous dipole forces |
| polar | covalent bond that forms between two atoms with very different electronegatvities |
