Lewis dot arrangement for NH3 is shown by the valence electrons surrounding the nitrogen atom.
The dot point arrangement in the case of NH3 displays that the nitrogen atom unites a solitary pair of e- with each of the three hydrogen atoms, resulting in a total of three shared pairs of electrons.
The ammonia molecule adopts a three-sided pyramid-like shape attributed to the placement of the valence electrons according to its Lewis dot arrangement.
In the dot symbol representation of NH3, the N atom is surrounded by three points, each representing a pair of shared electrons with a H atom.
