WebBivalent is a related term of univalent. In chemistry terms the difference between univalent and bivalent is that univalent is having a valence of 1, or having only one valence while bivalent is having a valence of 2. In genetics terms the difference between univalent and bivalent In chemistry, the valence (US spelling) or valency (British spelling) of an element is the measure of its combining capacity with other atoms when it forms chemical compounds or molecules.
