Electron pair dot arrangement in the case of ammonia is portrayed by the valence electrons surrounding the nitrogen atom.
The Lewis dot structure in the case of NH3 unveils that the nitrogen atom connects a solitary pair of electrons with each of the three hydrogen atoms, resulting in a complete of three shared pairs of electrons.
The ammonia molecule adopts a trigonal pyramidal structure attributed to the arrangement of the outer electrons according to its Lewis dot arrangement.
In the Lewis symbol representation of NH3, the nitrogen atom is enveloped by three dots, each representing a pair of joined electrons with a H atom.
