Lewis Beverage cup arrangement for ammonia is a representation of the outer electrons surrounding the nitrogen atom. The dot point structure in the case of ammonia displays that the N atom connects one pair of e- with each of the three hydrogen atoms, resulting in a complete of a trio shared pairs of electrons. The NH3 molecule takes a three-sided pyramid-like structure due to the arrangement of the valence electrons according to its Lewis Beverage cup arrangement. In the Lewis dotpoint depiction of ammonia, the N atom is encircled by three points, each representing a pair of connected electrons with a H atom.
