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 |
