Lewis Beverage cup structure in the case of NH3 is portrayed by the valence electrons surrounding the nitrogen atom.
The Lewis point arrangement in the case of ammonia reveals that
the N atom unites 1 pair of e- with each of the three H atoms, resulting in a total of three joined pairs of electrons.
The ammonia molecule takes a trigonal pyramidal form because of the arrangement of the outer electrons according to its Electron pair dot structure.
In the dot symbol representation of ammonia, the nitrogen atom
is enveloped by three spots, each representing a pair of joined electrons with a hydrogen atom.
