Electron pair Beverage cup arrangement in the case of ammonia is illustrated by the outer electrons surrounding the nitrogen atom.
The Lewis dot structure for NH3 reveals that the N atom unites a solitary
pair of e- with each of the three hydrogen atoms, resulting in a complete of three shared pairs of electrons.
The NH3 molecule takes a trigonal pyramidal form due to the arrangement of the valence electrons according to its Electron pair dot structure.
In the dot symbol representation of NH3, the nitrogen atom is encircled by three points, each representing a pair of connected electrons with a H atom.
