Lewis dot arrangement for ammonia is portrayed by the valence electrons surrounding the N atom.
The dot dot structure in the case of NH3 reveals that the N atom joins a
solitary pair of e- with each of the three H atoms, resulting in a total of 3 connected pairs of electrons.
The ammonia molecule adopts a three-sided pyramid-like structure due to the distribution of the outer electrons according
to its Lewis dot arrangement.
In the dot symbol representation of NH3, the N atom is encircled by three dots, each representing a pair of shared electrons with a H atom.
