9.1 Valence e- - Determines chemical properties --Because RXNs result in the gain, loss or rearrangement of e- -- what remains are core electrons and we do not “care” about them in chemical reactions -Main Group Elements --Group # = Valence e- --Accounts for similarity of chemical properties w/in a group --ns and ns np e-, see Table 9.2 pg. 375 -Transetion elements --ns (n-1)d orbital e- -- Again accounts for similarity of chemical properties w/in a group but with more complex interactions 9.2 Chemical Bond Formation - w/in a chemical RXN valence e- are reorganized so a NET ATTRACTIVE FORCE holds e- in place (Coulombs Law) -- Result is a chemical bond forms between atoms -3 General types of Bonds Ionic Covalent Metallic

- Ionic (Metal with non-metal) - e- transferred from one atom to the other -- metals looses e- and is oxidized --Nonmetal gains e- and is reduced -- Seen B/T atoms with large differences in their tendencies to gain or lose e- --- Left side with the Right side of the periodic table - The electrostatic attraction of (+) with (–) ions draws them into a 3 dimensional array of ionic solid
