Electron pair Beverage cup structure for ammonia is a representation of the valence electrons surrounding the N atom.
The Lewis point arrangement in the case of ammonia displays that the nitrogen atom unites a solitary pair of electrons with each of the three hydrogen atoms, resulting in a total of three united pairs of electrons.
The NH3 molecule takes a three-sided pyramid-like structure because of the placement of the valence electrons according to its Lewis dot structure.
In the dot symbol depiction of NH3, the N atom is enclosed by three spots, each representing a pair of shared electrons with a hydrogen atom.
