Lewis dot arrangement for ammonia is depicted by the outer electrons surrounding the nitrogen atom.
The Lewis dot structure for NH3 displays that the N atom joins a solitary pair of e- with each of the three hydrogen atoms, resulting in a overall of three connected pairs of electrons.
The ammonia molecule takes a three-sided pyramid-like structure attributed to the distribution of the valence electrons according to its Lewis dot structure.
In the Lewis symbol representation of ammonia, the nitrogen atom is encircled by three dots, each representing a pair of shared electrons with a H atom.
