Electron pair dot structure for NH3 is illustrated by the valence electrons surrounding the nitrogen atom. The dot dot structure for NH3 displays that the N atom shares one pair of electrons with each of the three H atoms, resulting in a total of a trio joined pairs of electrons. The NH3 molecule takes a three-sided pyramid-like form because of the distribution of the outer electrons according to its Lewis Beverage cup arrangement. In the dot dotpoint depiction of NH3, the nitrogen atom is encircled by three spots, each representing a pair of shared electrons with a hydrogen atom.
