Electron pair dot structure for NH3 is portrayed by the outer electrons surrounding the nitrogen atom. The Lewis dot structure for NH3 unveils that the N atom unites a solitary pair of e- with each of the three H atoms, resulting in a complete of three joined pairs of electrons. The NH3 molecule adopts a trigonal pyramidal structure attributed to the placement of the outer electrons according to its Lewis dot arrangement. In the Lewis symbol representation of ammonia, the N atom is enveloped by three points, each representing a pair of joined electrons with a hydrogen atom.
