Lewis Beverage cup structure for ammonia is illustrated by the valence electrons surrounding the nitrogen atom.
The Lewis point structure in the case of ammonia unveils that the N atom shares one pair of e- with each of the three hydrogen atoms, resulting in a overall of a trio shared pairs of electrons.
The NH3 molecule takes a trigonal pyramidal structure due to the arrangement of the valence electrons according to its Lewis dot arrangement.
In the Lewis symbol depiction of ammonia, the N atom is surrounded by three points, each representing a pair of shared electrons with a hydrogen atom.
