Lewis Beverage cup structure for NH3 is a representation of the valence electrons surrounding the N atom.
The Lewis dot arrangement in the case of NH3 exhibits that the N atom connects 1 pair of e- with each of the three H atoms, resulting in a overall of three joined pairs of electrons.
The ammonia molecule takes a three-sided pyramid-like structure because of the distribution of the valence electrons according to its Electron pair Beverage cup arrangement.
In the dot dotpoint depiction of ammonia, the nitrogen atom is enveloped by three spots, each representing a pair of united electrons with a H atom.
