The ammonia molecule has a trigonal pyramidal shape as predicted by the valence shell electron pair repulsion theory (VSEPR theory) with an experimentally determined bond angle of 106.7°. The central nitrogen atom has five outer electrons with an additional electron from each hydrogen atom.
Ammonia is a covalent atom. The particle is shaped because of the overlap of orbitals of three hydrogen atoms and three Sp

Ammonia is a covalent atom. The particle is shaped because of the overlap of orbitals of three hydrogen atoms and three Sp 3 hybrid orbitals of nitrogen in the structure as the central atom.
The fourth sp³ hybrid orbital is involved by a lone pair.
Due to this the shape of ammonia is trigonal pyramidal.
The H-N-H bond edge is 107.3°, which is somewhat not exactly the tetrahedral edge of 109°28.
