Lewis Beverage cup structure in the case of NH3 is a representation of the valence electrons surrounding the nitrogen atom.
The Lewis point structure for NH3 unveils that the N atom connects 1 pair of electrons with each of the three H atoms, resulting in a complete of a trio joined pairs of electrons.
The ammonia molecule adopts a three-sided pyramid-like structure attributed to the placement of the outer electrons according to its Lewis dot arrangement.
In the dot symbol representation of NH3, the nitrogen atom is encircled by three spots, each representing a pair of shared electrons with a hydrogen atom.
