Electron pair dot structure for ammonia is depicted by the valence electrons surrounding the nitrogen atom. The dot point arrangement for NH3 exhibits that the nitrogen atom connects a solitary pair of electrons with each of the three H atoms, resulting in a total of 3 joined pairs of electrons. The NH3 molecule adopts a trigonal pyramidal structure because of the arrangement of the valence electrons according to its Lewis Beverage cup arrangement. In the dot symbol representation of ammonia, the nitrogen atom is enveloped by three points, each representing a pair of united electrons with a H atom.
