Lewis Beverage cup arrangement in the case of ammonia is depicted by the valence electrons surrounding the nitrogen atom.
The Lewis dot arrangement for ammonia displays that the N atom joins 1 pair of e- with each of the three hydrogen atoms, resulting in a complete of three shared pairs of electrons.
The NH3 molecule takes a trigonal pyramidal structure because of the arrangement of the
valence electrons according to its Lewis Beverage cup structure.
In the Lewis dotpoint representation of ammonia, the N atom is surrounded by three dots, each
representing a pair of connected electrons with a hydrogen atom.
