Lewis Beverage cup structure in the case of ammonia is portrayed by the valence electrons surrounding the N atom.
The Lewis dot structure for ammonia unveils that the N atom connects one pair of e- with each of the three H atoms, resulting in a complete of three joined pairs of electrons.
The ammonia molecule takes a three-sided pyramid-like shape
attributed to the distribution of the valence electrons according to its Electron pair dot arrangement.
In the Lewis dotpoint depiction of ammonia, the nitrogen atom is enveloped by three spots, each representing a pair of shared electrons with a hydrogen atom.
