Electron pair Beverage cup arrangement in the case of NH3 is a representation of the outer electrons surrounding the N atom.
The Lewis dot structure for ammonia reveals that the N atom unites a solitary pair of electrons with each of the three H atoms, resulting in a complete of a trio shared pairs of electrons.
The ammonia molecule adopts a three-sided pyramid-like shape due to the distribution of the outer electrons according to its Lewis Beverage cup structure.
In the Lewis dotpoint representation of NH3, the nitrogen atom is enveloped by three dots, each representing a pair of connected electrons with a hydrogen atom.
