Lewis Beverage cup structure for ammonia is portrayed
by the valence electrons surrounding the N atom.
The dot point arrangement for NH3 exhibits that the N atom shares 1 pair of electrons with each of the three H atoms, resulting in a complete of three connected pairs of electrons.
The NH3 molecule
adopts a three-sided pyramid-like shape attributed to the distribution of the valence electrons according to its Electron pair Beverage cup structure.
In the dot symbol representation of NH3, the N atom is enveloped by three spots, each representing a pair of united electrons with a hydrogen atom.
