Electron pair Beverage cup arrangement for ammonia is illustrated by the valence electrons surrounding the nitrogen atom. The Lewis dot arrangement in the case of ammonia unveils that the N atom shares 1 pair of electrons with each of the three H atoms, resulting in a overall of 3 united pairs of electrons. The ammonia molecule takes a trigonal pyramidal form because of the placement of the outer electrons according to its Lewis Beverage cup arrangement. In the dot dotpoint depiction of ammonia, the nitrogen atom is enveloped by three points, each representing a pair of joined electrons with a hydrogen atom.
