Lewis Beverage cup structure in the case of ammonia is shown by the outer electrons surrounding the N atom.
The dot point arrangement for NH3 exhibits that the nitrogen atom shares one pair of e- with each of the three H atoms, resulting in a complete of three united pairs of electrons.
The NH3 molecule takes a three-sided pyramid-like form because of the distribution of the outer electrons according to its Electron pair dot structure.
In the dot dotpoint representation of ammonia, the N atom is surrounded by three points, each representing a pair of united electrons with a hydrogen atom.
