  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 Unshared Pairs F Cl

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

  5. Another way to look at Covalent Bonds • What makes the atom happy……8 val e- • Exceptions • Hydrogen (2) and Boron (6) Valence Electrons 8 + 8 = 16 6 + 6 = 12 O and S

  6. Another way to look at Covalent Bonds • Subtract to find the number of electrons that will be alone Divide by two to determine the number of bonds (2 electrons per bond…) 8 + 8 = 16 6 + 6 = - 12 O and S = 2 bonds 4 ÷ 2

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