Lewis Beverage cup arrangement for ammonia is a representation of the outer electrons surrounding
the nitrogen atom.
The Lewis point arrangement in the case of ammonia displays that the nitrogen atom unites one pair of e- with each of the three H atoms, resulting in a overall of 3 connected pairs of electrons.
The NH3 molecule adopts a trigonal pyramidal form due to the distribution of the valence electrons according to its Electron pair Beverage cup arrangement.
In the Lewis symbol representation of ammonia, the N atom is enveloped by three dots, each representing a pair of connected electrons with a hydrogen atom.
