Electron pair Beverage cup structure in the case of ammonia is a representation of the outer electrons surrounding the N atom. The Lewis dot structure for ammonia reveals that the N atom joins a solitary pair of e- with each of the three H atoms, resulting in a total of a trio shared pairs of electrons. The ammonia molecule adopts a three-sided pyramid-like structure attributed to the arrangement of the valence electrons according to its Lewis Beverage cup structure. In the Lewis dotpoint depiction of NH3, the N atom is enveloped by three points, each representing a pair of shared electrons with a hydrogen atom.
