Lewis dot structure for NH3 is shown by the outer electrons surrounding the N atom. The Lewis point structure for ammonia reveals that the nitrogen atom connects one pair of electrons with each of the three H atoms, resulting in a complete of a trio united pairs of electrons. The NH3 molecule adopts a three-sided pyramid-like form due to the distribution of the valence electrons according to its Lewis dot structure. In the dot dotpoint representation of NH3, the N atom is encircled by three dots, each representing a pair of connected electrons with a hydrogen atom.
