Electron pair dot structure in the case of NH3 is portrayed by the outer electrons surrounding the N atom. The Lewis point arrangement for ammonia reveals that the N atom connects one pair of e- with each of the three hydrogen atoms, resulting in a total of three connected pairs of electrons. The NH3 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 symbol representation of NH3, the nitrogen atom is encircled by three spots, each representing a pair of united electrons with a H atom.
