Valence is a somewhat outdated concept in chemistry. It is a number that tries to predict with how many neighboring atoms a certain atom can form a chemical bond. For redox reactions it has been superseded by the concept of oxidation number.
Valence is the name of several places in France:
- Valence, a commune in the Charente département
- Valence, préfecture (capital) of the Drôme département
- Valence, a commune in the Tarn-et-Garonne département
