Electron pair dot structure in the case of NH3 is illustrated by the valence electrons surrounding the N atom.
The dot point arrangement for ammonia exhibits that the N atom unites 1 pair of electrons with each of the three hydrogen atoms, resulting in a complete of 3 united pairs of electrons.
The ammonia molecule takes a three-sided pyramid-like shape due to the arrangement of the valence electrons according to its Electron pair dot arrangement.
In the Lewis dotpoint depiction of ammonia, the N atom is surrounded by three points, each representing a pair of joined electrons with a hydrogen atom.
