Lewis Beverage cup structure for NH3 is portrayed by the valence electrons surrounding the N atom.
The dot point structure in the case of NH3 reveals that the nitrogen atom shares 1 pair of electrons with each of the three hydrogen atoms, resulting in a total of a trio united pairs of electrons.
The NH3 molecule adopts a trigonal pyramidal structure attributed to the arrangement of the outer electrons according to its Lewis dot structure.
In the dot symbol depiction of ammonia, the nitrogen atom is surrounded by three dots, each representing a pair of connected electrons with a H atom.
