Lewis Beverage cup arrangement for ammonia is illustrated by the outer electrons surrounding the nitrogen atom.
The Lewis point structure in the case of ammonia reveals that the nitrogen atom joins 1 pair of e- with each of the three hydrogen atoms, resulting in a overall of 3 shared pairs of electrons.
The ammonia molecule takes a three-sided pyramid-like shape
attributed to the distribution of the valence electrons according to its Electron pair dot structure.
In the Lewis symbol depiction of NH3, the N atom is enclosed by three spots, each representing a pair of united electrons with a H atom.
