Electron pair Beverage cup arrangement for NH3 is depicted by
the outer electrons surrounding the nitrogen atom.
The dot dot structure in the case of NH3 exhibits that
the N atom unites a solitary pair of e- with each of the three hydrogen atoms, resulting in a overall of 3 united pairs of electrons.
The ammonia molecule takes a trigonal pyramidal form because of the distribution of the outer electrons according to its Lewis dot arrangement.
In the Lewis symbol depiction of NH3, the nitrogen atom is enveloped by three spots, each representing a pair of shared electrons with a hydrogen atom.
