35 Lewis Structures and Covalent Bonding Chemistry LibreTextsElectron pair dot arrangement for NH3 is depicted by the valence electrons surrounding the nitrogen atom.
The Lewis dot arrangement for ammonia reveals that the nitrogen atom connects one pair of e- with each of the three hydrogen atoms, resulting in a complete of three united pairs of electrons.
The ammonia molecule takes a three-sided pyramid-like shape attributed to the
placement of the outer electrons according to its Lewis dot arrangement.
In the Lewis dotpoint representation of ammonia, the nitrogen atom is enveloped by three points, each representing a pair of shared electrons with a hydrogen atom.
