Electron pair dot arrangement for ammonia is a representation of the outer electrons surrounding the nitrogen atom.
The dot dot structure for ammonia displays that the nitrogen atom joins a solitary pair of e- with each of the three hydrogen atoms, resulting in a total of a trio joined pairs of electrons.
The ammonia molecule adopts a trigonal pyramidal structure because of the arrangement of the valence electrons according to its Lewis dot arrangement.
In the Lewis symbol depiction of NH3, the N atom is encircled by three spots, each representing a pair
of united electrons with a hydrogen atom.
