Lewis dot structure for NH3 is a representation of the outer electrons surrounding the nitrogen atom.
The dot point structure in the case of NH3 displays that the N atom unites one pair of e- with each of the three H atoms, resulting
in a total of three connected pairs of electrons.
The ammonia molecule takes a trigonal pyramidal structure because of the arrangement of the valence electrons according to its Lewis dot structure.
In the Lewis dotpoint representation of NH3,
the nitrogen atom is enveloped by three points, each representing a pair of joined electrons with a hydrogen atom.
