Electron pair dot arrangement in the case of ammonia is depicted by the outer electrons surrounding the N atom. The Lewis point arrangement in the case of NH3 reveals that the N atom connects 1 pair of electrons with each of the three hydrogen atoms, resulting in a complete of 3 connected pairs of electrons. The ammonia molecule adopts a three-sided pyramid-like shape because of the distribution of the outer electrons according to its Electron pair dot arrangement. In the dot symbol representation of NH3, the nitrogen atom is surrounded by three dots, each representing a pair of shared electrons with a H atom.
