Electron pair Beverage cup
structure in the case of ammonia is depicted by the valence electrons surrounding the nitrogen atom.
The Lewis point arrangement in the case of ammonia exhibits that the nitrogen atom joins one pair of electrons with each of the three H atoms, resulting in a total of a trio connected pairs of electrons.
The NH3 molecule takes a three-sided pyramid-like shape due to
the distribution of the valence electrons according to its Lewis dot arrangement.
In the Lewis dotpoint depiction of NH3, the nitrogen atom is enclosed by three dots, each representing a pair of connected electrons with a H atom.
