Do Now • Build an oxygen molecule and an ammonia (NH3) molecule - Draw your model in your notes • Objective • Octet Rule, Single/Double/Triple Covalent Bonds, Coordinate Covalent Bonds • HW • Start your 8.2 questions on page 229
The Octet Rule Bonding Electron sharing usually occurs so that atoms attain the electron configuration of noble gases.
Single Bonds Ammonia Unshared or Lone Pair
Double Bonds • Carbon Dioxide
