Lewis dot arrangement for NH3 is a representation of the outer electrons surrounding the nitrogen atom. The Lewis point arrangement for NH3 reveals that the nitrogen atom unites one pair of e- with each of the three hydrogen atoms, resulting in a overall of a trio connected pairs of electrons. The ammonia molecule takes a three-sided pyramid-like structure attributed to the placement of the valence electrons according to its Lewis Beverage cup structure. In the Lewis dotpoint representation of NH3, the N atom is encircled by three points, each representing a pair of united electrons with a H atom.
