Lewis dot structure for NH3 is depicted by the outer electrons surrounding the N atom.
The dot point arrangement in the case of ammonia unveils that the N atom shares one pair of e- with each of the three H atoms, resulting in a overall of 3 shared pairs of electrons.
The ammonia molecule adopts a three-sided pyramid-like shape because of the arrangement of the valence electrons according to its Electron pair Beverage cup arrangement.
In the Lewis dotpoint representation of NH3, the N atom is enclosed by three spots, each representing a pair of joined electrons with a H atom.
