Lewis dot arrangement for ammonia is shown by the valence electrons surrounding the nitrogen atom.
The dot point structure in the case of ammonia reveals that the nitrogen atom joins a solitary pair of e- with each of the three H atoms, resulting in a total of three joined pairs of electrons.
The ammonia molecule takes a three-sided pyramid-like structure because of the distribution of the outer electrons according to its Electron pair dot arrangement.
In the Lewis dotpoint representation of ammonia, the N atom is encircled by three dots, each representing a pair of united electrons with a H atom.
