Lewis Beverage cup structure for ammonia is illustrated by the valence electrons surrounding the N atom. The dot point structure in the case of NH3 reveals that the N atom joins a solitary pair of electrons with each of the three H atoms, resulting in a complete of a trio connected pairs of electrons. The ammonia molecule takes a three-sided pyramid-like shape attributed to the placement of the valence electrons according to its Electron pair Beverage cup arrangement. In the Lewis dotpoint depiction of NH3, the N atom is surrounded by three points, each representing a pair of shared electrons with a H atom.
