Lewis dot arrangement for ammonia is illustrated by the outer electrons surrounding the nitrogen atom.
The Lewis dot structure for ammonia displays
that the nitrogen atom shares one pair of e- with each of the three H atoms, resulting in a overall of 3 joined pairs of electrons.
The ammonia molecule takes a trigonal pyramidal structure because of the distribution of the outer electrons according
to its Electron pair dot structure.
In the dot symbol representation of NH3, the N atom is encircled by three dots, each representing a pair of joined electrons with a hydrogen atom.
