Lewis dot arrangement in the case of ammonia is shown by the outer electrons surrounding the nitrogen atom.
The Lewis point structure
for ammonia unveils that the nitrogen atom connects a solitary pair of e- with each of the three H atoms, resulting in a overall of a trio connected pairs of electrons.
The NH3 molecule takes a trigonal pyramidal structure because of the placement of the valence electrons according to its Lewis dot arrangement.
In the Lewis symbol representation of NH3, the N atom is surrounded by three points, each representing a pair of connected electrons with a H atom.
