Workshop 14 Name: Part 2: Multiple Central Atoms Each of the following molecules has more than one central atom. Each needs to be analyzed sepa- rately, although for the first three examples the geometry will be identical at each. As before analyze and predict the geometry for each, then build the model to see if the predictions were correct or not. H2O2 (at each oxygen) Electron Domains linear bent pyramidal Bonded Atoms 180° 120 109 N2H2 (at each nitrogen) Electron...
