Lewis dot arrangement for ammonia is shown by the
outer electrons surrounding the N atom.
The dot dot arrangement in the case of ammonia
reveals that the nitrogen atom unites a solitary pair of e- with each of the three hydrogen atoms, resulting
in a complete of a trio shared pairs of electrons.
The ammonia molecule adopts a three-sided pyramid-like form due to the distribution of the outer electrons according to its Lewis dot arrangement.
In the Lewis dotpoint depiction of NH3, the nitrogen atom is enveloped by three spots, each
representing a pair of joined electrons with a hydrogen atom.
