What constitutes an electron domain in the VSEPR model?
Answer
A bonding pair (single, double, or triple) or a lone pair
An electron domain is defined as any region of electron density around the central atom, which includes both shared electron pairs (bonding pairs, regardless of multiplicity) and unshared electron pairs (lone pairs).
