|---|---|
| Polyatomic Ion | Charged group of covalently bonded atoms |
| Nonpolar Covalent | Electrons are shared equally by bonded electrons; balanced charge |
| Octet Rule | Outermost valence shell needs 8 electrons for stability |
| Stock System | Uses Roman numeral to indicate ion's charge |
| Ionic Bond | When electrons are transferred from a metal to a nonmetal |
| Polar Covalent | Bonded atoms have an unequal attraction for shared electrons; unbalanced charge |
| Electron-Dot Notation | only valence electrons of an element are placed around the element symbol |
| Metallic Bond | Delocalized electrons move freely among positively charged ions |
| Oxidation # | Number assigned to the charge of an ion in building compounds |
| Covalent Bond | When electrons are shared between two nonmetals |
