Lewis Beverage cup structure for ammonia is illustrated by the valence electrons surrounding the nitrogen atom.
The dot dot arrangement in the case of NH3 unveils that the nitrogen atom unites one pair of e-
with each of the three H atoms, resulting in a complete of a trio connected pairs of electrons.
The NH3 molecule adopts a three-sided pyramid-like form because of the placement of the valence electrons according to its Electron pair dot structure.
In the Lewis symbol representation of ammonia, the N atom is encircled by three dots, each representing a pair of shared electrons with a hydrogen atom.
