Electron pair Beverage cup arrangement in the case of ammonia is illustrated by the valence electrons surrounding the nitrogen atom.
The dot dot structure in the case of ammonia displays that the nitrogen atom connects one pair of e- with each of the three H atoms, resulting in a overall of 3 joined pairs of electrons.
The ammonia molecule takes a three-sided pyramid-like form because of the distribution of the outer electrons according to its Lewis Beverage cup arrangement.
In the Lewis dotpoint depiction of ammonia, the N atom is enclosed by three
dots, each representing a pair of united electrons with a H atom.
