Lewis dot structure for ammonia is a representation of the valence electrons surrounding the N atom.
The Lewis dot arrangement for ammonia reveals that the nitrogen atom unites a solitary pair of e- with each of the three H atoms, resulting in a complete of 3 connected pairs of electrons.
The NH3 molecule adopts a three-sided pyramid-like shape due to the placement of the outer electrons according to its Electron pair dot arrangement.
In the Lewis dotpoint depiction of NH3, the nitrogen atom is surrounded by three dots, each representing a pair of shared electrons with a H atom.
