Electron pair Beverage cup arrangement for NH3 is illustrated by the outer electrons surrounding
the nitrogen atom.
The dot dot structure for NH3 displays that the nitrogen atom joins 1 pair of e- with each of the three hydrogen atoms, resulting in a overall of a trio shared pairs of electrons.
The NH3 molecule adopts a three-sided pyramid-like structure because of the distribution of the valence electrons according to its Lewis dot structure.
In the dot symbol representation of ammonia, the N atom is encircled by three spots, each representing a pair of connected electrons with a hydrogen
atom.
