Electron pair dot structure for NH3 is shown by the valence electrons surrounding the nitrogen atom. The dot point structure for NH3 exhibits that the nitrogen atom joins a solitary pair of electrons with each of the three hydrogen atoms, resulting in a total of a trio connected pairs of electrons. The ammonia molecule takes a trigonal pyramidal form because of the distribution of the valence electrons according to its Electron pair dot structure. In the dot symbol depiction of ammonia, the nitrogen atom is enveloped by three dots, each representing a pair of joined electrons with a hydrogen atom.
