1 Another Look at Bonding

2 Ionic Bonds Drawing the bond Mg and Cl Write the Oxidation numbers Mg +2 and Cl -1 Mg +2 Cl -1

3 Covalent Bonds Bonding Sites Cl and F Cl F Unshared Pairs

4 Covalent Bonds Bonding Sites Cl F Bonding Site (Find lonely Electron) Shared Pair

5 Another way to look at Covalent Bonds What makes the atom happy……8 val e - Exceptions – Hydrogen (2) and Boron (6) O and S = = 12 Valence Electrons

6 Another way to look at Covalent Bonds Subtract to find the number of electrons that will be alone O and S = = ÷ 2 Divide by two to determine the number of bonds (2 electrons per bond…) = 2 bonds

7 Final Product of O and S O S 2 bonds Lone Pairs or Unshared Pairs 8 valence e -
