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