ionic bonding chemical bonding that results from the electrical attraction between large numbers of cations and anions covalent bonding results from the sharing of electron pairs between two atoms valence electrons electrons on the outermost energy level of an atom oxidation numbers Shows how many electrons can be shared, lost or gained to become stable octet rule States that atoms lose, gain or share electrons in order to acquire a full set of eight valence electrons criss-cross method A strategy for writing formulas of ionic compounds in which the charge of one ion becomes the subscript of the other; the result is a ratio of ions that produces a zero net charge for the ionic compound as a whole electron dot diagram a model of an atom in which each dot represents a valence electron (also called "Lewis dot diagram" Bohr model model of the atom in which electrons move rapidly around the nucleus in paths called orbits Chemical bond the attractive force that holds atoms or ions together polyatomic ion a charged group of covalently bonded atoms metallic bonding the chemical bonding that results from the attraction between metal atoms and the surrounding sea of electrons polar bonds bonds in which electrons are not shared equally between atoms of different elements in a compound. nonpolar bonds bonds in which electrons are shared equally between two atoms of the same element in a compound. alloy a mixture of metals
