| chemical bond | mutual electrical attraction between the nuclei and valence electrons |
| ionic bonding | chemical bonding that results from the electrical attraction between large numers of cation and anions |
| covalent bonding | the sharing of electron pairs |
| nonpolar-covalent bond | bonded electrons are shared equally |
| polar covalent bond | bonded atoms have unequal attration |
