Lewis Beverage cup structure in the case of NH3 is illustrated by the outer electrons surrounding the N atom. The Lewis dot structure in the case of ammonia exhibits that the N atom joins a solitary pair of e- with each of the three hydrogen atoms, resulting in a total of three joined pairs of electrons. The ammonia molecule adopts a three-sided pyramid-like form due to the distribution of the valence electrons according to its Electron pair Beverage cup arrangement. In the dot dotpoint representation of NH3, the nitrogen atom is encircled by three spots, each representing a pair of joined electrons with a H atom.
