Electron pair Beverage cup arrangement for NH3 is depicted by the outer
electrons surrounding the N atom.
The dot dot arrangement in the case of NH3 reveals that the N atom unites one pair of electrons with each of the three hydrogen atoms, resulting in a overall of 3 united pairs of electrons.
The ammonia molecule adopts a trigonal pyramidal form attributed to the placement of the outer electrons according to its Electron pair Beverage cup arrangement.
In the Lewis dotpoint representation of ammonia, the N atom is surrounded by three dots, each representing a pair of united electrons with a H atom.
