| covalent bond | sharing one or more electron pairs |
| ionic bond | transfer of one or more electrons |
| salt | formed from anion of acid and cation of base |
| molcule | neutral group of atoms bonded covalently |
| metallic bond | attractive force between fixed positive ion and valence electrons in a metal |
| hydrogen bond | intermolecular force of attraction |
| electronegativity | measure of strength of attraction of electrons in an atom forming a chemical bond |
| octet rule | to obtain a full set of valence electrons, atoms will share, gain or lose electrons |
| nonpolar covalent | a bond between 2 atoms having equal or similar electronegativities |
| polar covalent | unequal sharing of electrons between atoms |
