In an ammonia molecule (NH3), nitrogen is the central atom. Nitrogen has four electron groups: Three N-H bonds and one lone electron pair. In a perfect tetrahedral structure, bond angles are 109.5 degrees. Would the bond angles between hydrogen molecules in ammonia be more, less, or equal to 109.5 degrees?
