Lewis Beverage cup arrangement in the case of ammonia is portrayed by the valence electrons surrounding the N atom.
The dot dot arrangement in the case of NH3 reveals that the nitrogen atom unites one pair of e- with each of the three hydrogen atoms, resulting in a complete of three joined pairs of electrons.
The ammonia molecule adopts a trigonal pyramidal structure due to the placement of the valence electrons according to its Electron pair dot structure.
In the Lewis symbol representation of ammonia, the N atom is enclosed by three dots, each representing a pair of joined electrons with a hydrogen atom.
