Lewis dot structure for NH3 is portrayed by the valence electrons surrounding the nitrogen atom.
The dot point structure in the case of NH3 reveals that the nitrogen atom connects a solitary pair of electrons with each of the three hydrogen atoms, resulting in a total of a trio shared pairs of electrons.
The ammonia molecule adopts a trigonal pyramidal structure due to the placement of the outer electrons according to its Lewis dot structure.
In the Lewis symbol representation of ammonia, the nitrogen atom is enclosed by three spots, each representing a pair of united electrons with a hydrogen atom.
