Electron pair dot arrangement in the case of NH3 is shown by the outer electrons surrounding the N atom.
The Lewis dot structure in the case of ammonia reveals that the nitrogen atom unites one pair of electrons with each of the three H atoms, resulting in a complete of 3 shared pairs of electrons.
The ammonia molecule adopts a three-sided pyramid-like form due to the arrangement of the outer electrons according to its Lewis dot arrangement.
In the Lewis symbol
representation of ammonia, the N atom is encircled by three points, each representing a pair of shared electrons with a hydrogen atom.
