Lewis Beverage cup structure in the case of ammonia is depicted by the outer electrons surrounding the nitrogen atom. The dot point structure for ammonia displays that the N atom connects one pair of e- with each of the three H atoms, resulting in a overall of three joined pairs of electrons. The ammonia molecule adopts a three-sided pyramid-like structure due to the placement of the outer electrons according to its Lewis dot arrangement. In the dot dotpoint depiction of ammonia, the nitrogen atom is enclosed by three points, each representing a pair of united electrons with a hydrogen atom.
