Electron pair Beverage cup arrangement in the case of NH3 is depicted by the valence electrons surrounding the N atom. The dot point arrangement in the case of NH3 unveils that the N atom unites a solitary pair of e- with each of the three H atoms, resulting in a total of three shared pairs of electrons. The NH3 molecule adopts a trigonal pyramidal shape due to the arrangement of the outer electrons according to its Electron pair dot structure. In the dot symbol representation of ammonia, the nitrogen atom is enveloped by three spots, each representing a pair of shared electrons with a hydrogen atom.
