- For the simulation, the model for two lone pairs of electrons attached to a central atom with two single bonds (H2O or OF2) shows a bond angle of 109.5. The bond angle should be 104.5. 12-2-1
- Having been in a number of conversations with the Phet help desk I appreciate that the simulation is not perfect at this point. That said, it's worth also knowing that the simulation doesn't take into account double or triple bond affects on molecular geometry for non-resonance molecules. This is not likely to be an issue for the standard honors/college prep type chemistry class, but if you driving at a level higher than this (AP or college level) you want to be aware of it. 12-2-10
