Lewis dot arrangement in the case of ammonia is depicted by the valence electrons surrounding the N atom.
The dot point arrangement in the case of ammonia unveils that the N atom unites 1 pair of electrons with each of the three hydrogen atoms, resulting in a overall of 3 shared pairs of electrons.
The NH3 molecule takes a trigonal pyramidal form due to the arrangement of the
valence electrons according to its Lewis dot arrangement.
In the Lewis symbol representation of NH3, the N atom is enclosed by three spots, each representing a pair of connected electrons with a H atom.
