Valence (chemistry)
The valence or valence of an atom is the highest number of monovalent atoms (originally hydrogen and chlorine ) that can be bonded to an atom of a chemical element .
It was introduced in 1852 by the English chemist Sir Edward Frankland , expanded many times and now stands for the following terms in different areas of chemistry, depending on the context:
- Ionic valency ( ionic charge )
- Binding (binding value, binding capacity, covalency)
- coordinative value ( coordination number )
- electrochemical valence or oxidation number
- Valence of alcohols
