Lewis dot arrangement in the case of NH3 is illustrated by the valence electrons surrounding the nitrogen atom.
The dot dot structure in the case of NH3 reveals that the nitrogen atom joins one pair of electrons with each of the three H atoms, resulting in a overall of 3 united pairs of electrons.
The ammonia molecule adopts a three-sided pyramid-like structure due to the arrangement of the outer electrons according to its Electron pair dot structure.
In the Lewis symbol representation of NH3, the nitrogen atom is enveloped by three spots, each representing a pair of shared electrons with a H atom.
