Electron pair Beverage cup arrangement for ammonia is illustrated by the outer electrons surrounding the N atom. The dot dot structure in the case of ammonia reveals that the N atom connects one pair of e- with each of the three H atoms, resulting in a complete of a trio united pairs of electrons. The NH3 molecule takes a trigonal pyramidal structure because of the placement of the valence electrons according to its Lewis Beverage cup structure. In the Lewis dotpoint representation of NH3, the nitrogen atom is encircled by three points, each representing a pair of connected electrons with a H atom.
