Lewis Beverage cup arrangement in the case of NH3 is illustrated by the outer electrons surrounding the nitrogen atom.
The dot dot structure in the case of ammonia displays that the N atom connects one pair of electrons with each of the three hydrogen atoms, resulting in a total of 3 united pairs of electrons.
The ammonia molecule takes a three-sided pyramid-like form attributed to the arrangement of the valence electrons according to its Electron pair dot structure.
In the Lewis dotpoint representation of ammonia, the
nitrogen atom is enclosed by three points, each representing a pair of shared electrons with a H atom.
