Lewis dot arrangement in the case of ammonia is portrayed by the outer electrons surrounding the N atom. The dot point structure in the case of ammonia exhibits that the nitrogen atom connects 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 takes a trigonal pyramidal structure due to the distribution of the outer electrons according to its Electron pair Beverage cup structure. In the Lewis dotpoint depiction of NH3, the nitrogen atom is enveloped by three spots, each representing a pair of connected electrons with a H atom.
