Lewis Beverage cup arrangement in the case of ammonia is portrayed by the outer electrons surrounding the N atom. The Lewis dot arrangement for NH3 exhibits that the N atom unites a solitary pair of electrons with each of the three H atoms, resulting in a total of three joined pairs of electrons. The NH3 molecule adopts a three-sided pyramid-like structure attributed to the arrangement of the outer electrons according to its Electron pair Beverage cup structure. In the Lewis symbol depiction of ammonia, the nitrogen atom is surrounded by three dots, each representing a pair of shared electrons with a H atom.
