Lewis Beverage cup arrangement in the case of ammonia is portrayed by the valence electrons surrounding the nitrogen atom.
The dot dot structure in the case of ammonia exhibits that the nitrogen atom shares one pair of electrons with each of the three hydrogen atoms, resulting in a overall of 3 joined pairs of electrons.
The ammonia molecule takes a trigonal pyramidal shape due to the distribution of the outer electrons according to its Lewis dot structure.
In the Lewis symbol representation of ammonia, the N atom is enveloped by three points, each representing a pair of joined electrons with a
hydrogen atom.
