Lewis dot structure for NH3 is depicted by the outer electrons surrounding the N atom.
The dot dot structure in the case of ammonia exhibits that the N atom connects 1 pair of electrons with each of the three hydrogen atoms, resulting in a complete of three united pairs of electrons.
The NH3 molecule takes a trigonal pyramidal shape due to the placement of the valence electrons according to its Lewis Beverage cup structure.
In the Lewis dotpoint representation of ammonia, the nitrogen atom is enveloped by three points, each representing a pair of joined electrons with a hydrogen atom.
