Lewis Beverage cup structure in the case of NH3 is illustrated by the valence electrons surrounding the N atom. The Lewis dot arrangement in the case of ammonia displays that the nitrogen atom joins 1 pair of electrons with each of the three hydrogen atoms, resulting in a total of 3 connected pairs of electrons. The NH3 molecule takes a trigonal pyramidal shape because of the arrangement of the valence electrons according to its Lewis Beverage cup structure. In the Lewis symbol representation of NH3, the N atom is enclosed by three spots, each representing a pair of joined electrons with a hydrogen atom.
