Lewis Beverage cup arrangement in the case of ammonia is shown by the valence electrons surrounding the N atom. The Lewis point arrangement in the case of ammonia displays that the N atom joins a solitary pair of electrons with each of the three H atoms, resulting in a overall of 3 joined pairs of electrons. The ammonia molecule takes a trigonal pyramidal structure because of the arrangement of the outer electrons according to its Lewis dot structure. In the dot symbol representation of ammonia, the N atom is enclosed by three points, each representing a pair of united electrons with a H atom.
