Lewis Beverage cup structure for NH3 is depicted by the outer electrons surrounding the N atom. The Lewis point arrangement in the case of ammonia displays that the nitrogen atom joins one pair of electrons with each of the three H atoms, resulting in a complete of three joined pairs of electrons. The ammonia molecule adopts a trigonal pyramidal shape attributed to the distribution of the valence electrons according to its Lewis dot arrangement. In the Lewis symbol depiction of ammonia, the nitrogen atom is enveloped by three dots, each representing a pair of shared electrons with a hydrogen atom.
