Lewis Beverage cup arrangement for ammonia is a representation of the valence electrons surrounding the nitrogen atom.
The dot point
arrangement for ammonia reveals that the nitrogen atom connects one pair of electrons with each of the three hydrogen atoms, resulting in a complete of a trio connected pairs of electrons.
The NH3 molecule adopts a trigonal pyramidal form attributed to the placement of the valence electrons according to its Electron pair dot structure.
In the dot dotpoint representation of ammonia, the N atom is enveloped by three spots, each representing a pair of united electrons with a hydrogen atom.
