Lewis dot structure in the case of NH3 is portrayed by the valence electrons surrounding the nitrogen atom.
The Lewis
dot structure for ammonia exhibits that the nitrogen atom shares 1 pair of electrons with each of the three H atoms, resulting in a overall of 3 connected pairs of electrons.
The ammonia molecule adopts a three-sided pyramid-like structure because of the distribution of the outer electrons according to its Electron pair Beverage cup arrangement.
In the dot dotpoint representation of ammonia, the nitrogen atom is enclosed by
three points, each representing a pair of connected electrons with a H atom.
