Lewis Beverage cup arrangement in the case of NH3 is a representation of the outer electrons surrounding the nitrogen atom.
The Lewis point structure in the case of NH3 unveils that the N atom unites one pair of e- with each of the three hydrogen atoms, resulting in a overall of three shared pairs of electrons.
The NH3 molecule adopts a three-sided
pyramid-like form due to the placement of the outer electrons according to its Lewis dot arrangement.
In the dot symbol representation of NH3, the N atom is enveloped by three points, each representing a pair of connected electrons with a hydrogen atom.
