Ionic compound- Metal reacts with a nonmetal Coulombs law- interaction between pair of ions. E= (2.31X 10^-19 J* nm) (Q1Q2/r) A bond will form if the energy of the aggregate is lower than that of the separated atoms. Covalent bonds- type of bonding in which electrons are shared by nuclei. (i.e Hydrogen bonding) Polar Covalent Bond- Atoms are different enough that they have unequal sharing results. 8.2-
