Lewis Beverage cup structure in the case of ammonia is a representation of
the valence electrons surrounding the nitrogen atom.
The dot point arrangement in the case of ammonia exhibits that the N atom unites a solitary pair of electrons with each of the three hydrogen atoms, resulting in a complete of three joined pairs of electrons.
The NH3 molecule takes a trigonal pyramidal structure because of the placement of the outer electrons according to its Lewis dot structure.
In the Lewis dotpoint depiction of ammonia, the nitrogen atom is enclosed by three points, each representing a pair of shared electrons with a H atom.
