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