Lewis dot structure for NH3 is depicted by the valence electrons surrounding the nitrogen atom.
The dot point structure for NH3 reveals that the nitrogen atom joins one pair of e- with each of the three hydrogen atoms, resulting in a overall of 3 shared pairs of electrons.
The ammonia molecule takes a three-sided pyramid-like structure because of the arrangement of the valence electrons according to its Electron pair dot arrangement.
In the Lewis dotpoint representation of NH3, the N atom is encircled by three points, each representing a pair of united electrons with a H atom.
