| Ionic Bond | formed when atoms exchange electrons. |
| Ionic Bond | Forms a Crystal Lattice |
| Ionic Bond | Forms between metals and nonmetals |
| Covalent Bond | formed when atoms share electrons |
| Covalent Bond | forms molecules |
| Covalent Bond | formed between 2 or more nonmetals |
| Metallic Bond | has free flowing electrons |
| Metallic Bond | formed between 1 or more metals |
| Valence Electrons / Electrons Available for Bonding | electrons in the outermost electron shell |
| Ion | an atom with a charge |
| Cation | an atom with a positive charge |
| Anion | An ion with a negative charge |
| Electrostatic Attraction | Attraction between a positive and a negative; holds ionic bonds together |
| Electronegativity | ability of an atom to attract electrons |
| Electronegativity | Fluorine has the highest |
| Ionization Energy | energy needed to remove an electron from an atom |
| Ionization Energy | Helium has the highest because it does not want to lose electrons |
