Lewis Beverage cup structure for ammonia is illustrated by the outer electrons surrounding the nitrogen atom.
The dot point arrangement for ammonia reveals that the N atom shares a solitary pair of e- with each of the three hydrogen atoms, resulting in a total of three joined pairs of electrons.
The NH3 molecule adopts a three-sided pyramid-like form attributed to the placement of the valence electrons according to its Lewis dot arrangement.
In the Lewis symbol depiction of ammonia, the N atom is encircled by three spots, each representing a pair of united electrons with a hydrogen atom.
