Lewis dot structure for NH3 is a representation of the valence electrons surrounding the N atom.
The dot dot arrangement for ammonia exhibits that the nitrogen atom shares one pair of e- with each of the three H atoms, resulting in a total of a trio connected pairs of electrons.
The ammonia molecule adopts a trigonal pyramidal form attributed to the distribution of the outer electrons according to its Lewis Beverage cup structure.
In the Lewis dotpoint representation of NH3, the nitrogen atom is encircled by three points, each representing a pair of shared electrons with a hydrogen atom.
