After addition of electron, the bond angle decreases and when you remove an electron domain then bond angle increases.

  • The bond angle decreases due to addition of electron lone pairs, which cause more repulsion on the bond pairs and as a result the bond pairs tend to come closer.
  • However the bond angle decreases when the electro-negativities of ligand atoms are more than that of central atom.
  • The bond angle increases due to remove of electron lone pairs, which decreases repulsion between bond pair and electron lone pair and as a result the bond pairs tend to go slightly away.
