Electron pair dot structure for ammonia is a representation of the outer electrons surrounding the nitrogen atom. The dot point structure in the case of ammonia exhibits that the N atom joins a solitary pair of electrons with each of the three hydrogen atoms, resulting in a total of three shared pairs of electrons. The ammonia molecule takes a trigonal pyramidal shape due to the arrangement of the valence electrons according to its Lewis dot structure. In the Lewis dotpoint depiction of NH3, the nitrogen atom is encircled by three dots, each representing a pair of united electrons with a hydrogen atom.
