Lewis dot structure for NH3 is shown by the valence electrons surrounding the N atom. The dot point arrangement in the case of NH3 exhibits that the nitrogen atom shares a solitary pair of electrons with each of the three H atoms, resulting in a total of three connected pairs of electrons. The NH3 molecule takes a three-sided pyramid-like form due to the arrangement of the outer electrons according to its Electron pair Beverage cup arrangement. In the dot dotpoint depiction of ammonia, the nitrogen atom is surrounded by three dots, each representing a pair of united electrons with a hydrogen atom.
