Lewis dot arrangement for ammonia is shown by the valence electrons surrounding the N atom.
The Lewis dot arrangement in the case of NH3 unveils that the nitrogen atom joins one pair of e- with each of the three H atoms, resulting in a complete of a trio connected pairs of electrons.
The ammonia molecule adopts a trigonal pyramidal form due to the placement of the outer electrons according to its Electron pair dot arrangement.
In the Lewis dotpoint representation of NH3, the nitrogen atom is enveloped by three points, each representing a pair of connected electrons with a hydrogen atom.
