Lewis Beverage cup arrangement in the case of NH3 is shown by the valence electrons surrounding the nitrogen atom.
The dot dot arrangement for NH3 displays that the N atom joins 1 pair of e- with each of the three
hydrogen atoms, resulting in a total of 3 united pairs of electrons.
The ammonia molecule takes a three-sided pyramid-like structure because of the distribution of the outer
electrons according to its Electron pair Beverage cup structure.
In the Lewis dotpoint depiction of ammonia, the nitrogen atom is encircled by three dots, each representing a pair of
united electrons with a hydrogen atom.
