Lewis dot arrangement in the case of ammonia is portrayed by the outer electrons surrounding the nitrogen atom.
The Lewis dot arrangement for ammonia displays that the N atom connects a solitary pair of electrons 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 because of the arrangement of the
outer electrons according to its Electron pair Beverage cup structure.
In the Lewis symbol depiction of NH3, the nitrogen atom is enveloped by three spots, each representing a pair of shared electrons with a H atom.
