| VALENCE ELECTRONS | ELECTRONS FOUND IN THE OUTER |
| ENERGY LEVEL | any of the poissible energies an electron may have in an atome |
| ORBITAL | A region in an atom where there is a high probability of finding electrons |
| FAMILY | vertical column on periodic table, also known as a group; elements have similar chemical and physical properties and same number of valance electrons |
| PERIOD | horizontal row of elements; elements in the same row have same number of orbitals |
| LEWIS STRUCTURE | drawing of a molecule that illustrates the valence electrons for the element |
| ELECTRON CLOUD | current theory or model of the atom where electrons move three dimensionally within a given area |
| CATION | result of an element changing from neutral state to positive because the element gave up electrons |
| ANION | result of an element changing from neutral state to negative as a result of gaining electrons |
| ION | charged particle as a result of losing or gaining electrons |
| CORE ELECTRONS | electrons that are NOT in the outer orbital/shell of the atom |
| OCTET RULE | max of eight valence electrons; full outer shell |
| MAIN GROUP ELEMENTS | elements that do not include transition or rare earth metals |
| 3rd orbital or energy level | M shell |
| ELECTRONEGATIVITY | The ability for an atom to attract electron. |
| 6 | number of valence electrons for oxygen |
| single bond | A chemical bond formed when atoms share one pair of electrons. |
| double bond | A chemical bond formed when atoms share two pairs of electrons. |
| polar bond | A covalent bond in which electrons are shared unequally. |
| non-polar bond | A covalent bond in which electrons are shared equally. |
