Lewis Beverage cup arrangement in the case of NH3 is shown by the outer electrons surrounding the nitrogen atom. The dot point arrangement for ammonia displays that the N atom connects a solitary pair of electrons with each of the three H atoms, resulting in a complete of three connected pairs of electrons. The ammonia molecule adopts a three-sided pyramid-like structure because of the distribution of the outer electrons according to its Lewis Beverage cup structure. In the dot symbol depiction of ammonia, the N atom is enclosed by three spots, each representing a pair of shared electrons with a H atom.
