Bonding: Ionic, Covalent Ionic: metal and nonmetal transfer e- Covalent: 2 nonmetals sharing e- Lattice Energy= Q1Q2/r KBr, KCl, SrO, CaO The Octect Rule is the tendency of an atom to want to have 8 valence electrons Covalent bond is the sharing of a pair of electrons b/w two atoms Double bonds: sharing of two pairs of e-s b/w two atoms Triple bond: sharing of 3 pairs of e-s b/w 2 atoms Octect deficient has less then 8 electrons Valence Shell Expansion more then 8 e- in outer shell VSEPR- Valence-shell electron –pair repulsion model-predicts the shapes of molecules and ions in which valence-shell electron-pairs are arranged about each atom so that electron-pairs are kept as far apart from one another as possible, thus minimizing electron-pair repulsion Electron groups (steric number, SN)- lone pair and any group that’s bonded (double and triple bonds= 1 electron group) When all electron groups are bonded, arrangement group and geometry are the same, once some electron groups are lone pairs, the names of the
