Lewis dot structure for ammonia is portrayed by the outer electrons surrounding the N atom. The Lewis dot structure in the case of NH3 exhibits that the nitrogen atom unites a solitary pair of electrons with each of the three hydrogen atoms, resulting in a complete of three shared pairs of electrons. The ammonia molecule takes a trigonal pyramidal structure because of the distribution of the valence electrons according to its Lewis Beverage cup structure. In the dot symbol depiction of NH3, the N atom is enclosed by three dots, each representing a pair of connected electrons with a hydrogen atom.
