Electron pair Beverage cup arrangement for ammonia is a representation of the outer electrons surrounding the N atom.
The dot point arrangement
in the case of ammonia unveils that the nitrogen atom joins 1 pair of e- with each of the three H atoms, resulting in a total of a trio united pairs of electrons.
The ammonia molecule adopts a three-sided pyramid-like structure attributed to the placement of the valence electrons according to its Lewis Beverage cup arrangement.
In the Lewis dotpoint representation of NH3, the N atom
is encircled by three spots, each representing a pair of united electrons with a H atom.
