The observed value of the H-N-H bond angle in ammonia is 107.3°, which is less than the ideal tetrahedral angle of 109.5°. This can be attributed to the lone pair of electrons on the nitrogen atom, which occupies more space than a bonding pair of electrons and therefore causes a repulsion that compresses the bond angle.
