Electron pair dot structure in the case of NH3 is illustrated by the outer electrons surrounding the nitrogen atom. The dot point arrangement in the case of NH3 displays that the nitrogen atom unites a solitary pair of e- with each of the three H atoms, resulting in a complete of three connected pairs of electrons. The NH3 molecule takes a three-sided pyramid-like form attributed to the placement of the valence electrons according to its Lewis dot structure. In the dot dotpoint representation of NH3, the N atom is encircled by three dots, each representing a pair of joined electrons with a H atom.
