Electron pair dot arrangement in the case of ammonia is shown by the outer electrons surrounding the N atom.
The Lewis point structure in the case of NH3 unveils that the N atom unites 1 pair of e- with each
of the three hydrogen atoms, resulting in a overall of a trio shared pairs of electrons.
The ammonia molecule adopts a three-sided
pyramid-like shape due to the arrangement of the outer electrons according to its Lewis Beverage cup arrangement.
In the dot dotpoint representation of ammonia, the nitrogen atom is enveloped by three spots, each representing a pair of joined electrons with a hydrogen atom.
