Electron pair dot structure for NH3 is shown by the outer electrons surrounding the nitrogen atom. The Lewis dot structure in the case of NH3 displays that the nitrogen atom unites a solitary pair of e- with each of the three hydrogen atoms, resulting in a overall of 3 shared pairs of electrons. The ammonia molecule takes a three-sided pyramid-like structure attributed to the distribution of the outer electrons according to its Lewis Beverage cup arrangement. In the Lewis symbol representation of ammonia, the N atom is enveloped by three dots, each representing a pair of shared electrons with a hydrogen atom.
