Lewis Beverage cup structure for NH3 is portrayed by the valence electrons surrounding the N atom. The Lewis point arrangement for ammonia reveals that the N atom connects one pair of e- with each of the three H atoms, resulting in a overall of a trio connected pairs of electrons. The NH3 molecule takes a trigonal pyramidal shape attributed to the distribution of the valence electrons according to its Electron pair Beverage cup arrangement. In the Lewis dotpoint representation of NH3, the N atom is encircled by three spots, each representing a pair of shared electrons with a H atom.
