Lewis Beverage cup structure in the case of ammonia is shown by the outer electrons surrounding the N atom. The dot dot structure in the case of ammonia displays that the N atom joins a solitary pair of electrons with each of the three hydrogen atoms, resulting in a overall of three united pairs of electrons. The ammonia molecule takes a trigonal pyramidal structure due to the distribution of the valence electrons according to its Lewis Beverage cup structure. In the dot dotpoint depiction of ammonia, the nitrogen atom is enclosed by three dots, each representing a pair of shared electrons with a hydrogen atom.
