Predict the bond angles and shape of a molecule of ammonia.

  1. There are four (4) groups of electrons around the central nitrogen atom (3 shared pairs and one lone pair of electrons)2) According to electron repulsion theory, the electrons move further away from each other, increasing the distance between them as much as possible.3) Shared pair: Lone pair exerts a greater repulsion and minimises the bond angle further.4) Bond angle- 107 degrees5) Shape- Trigonal Pyramidal This answer is predicted according to valence shells electron repulsion theory (VSEPR).
