Lewis Beverage cup structure in the case of ammonia is portrayed by the outer electrons surrounding the N atom. The Lewis dot structure for NH3 unveils that the nitrogen atom joins a solitary pair of e- with each of the three hydrogen atoms, resulting in a complete of a trio connected pairs of electrons. The NH3 molecule adopts a trigonal pyramidal shape due to the distribution of the valence electrons according to its Lewis Beverage cup arrangement. In the Lewis dotpoint depiction of ammonia, the N atom is encircled by three dots, each representing a pair of connected electrons with a hydrogen atom.
