Lewis dot arrangement in the
case of NH3 is portrayed by the outer electrons surrounding the N atom.
The Lewis dot structure for NH3 exhibits that the N atom shares one pair of e- with each of the three hydrogen atoms, resulting in a overall of three joined pairs of electrons.
The ammonia molecule takes a trigonal pyramidal form because of the arrangement of the valence electrons according to its Electron pair dot arrangement.
In the Lewis dotpoint representation of NH3, the nitrogen atom is enveloped by three dots, each representing a pair of shared electrons with a H atom.
