Electron pair dot arrangement in the case of ammonia is illustrated by the outer electrons surrounding the N atom.
The dot dot arrangement for NH3 reveals that the N atom joins one pair of electrons with each of the three H atoms, resulting in a complete of three joined pairs of electrons.
The ammonia molecule takes a three-sided pyramid-like form because of the arrangement
of the outer electrons according to its Lewis Beverage cup arrangement.
In the dot dotpoint depiction of NH3, the N atom is surrounded by three points, each representing a pair of connected electrons with a hydrogen atom.
