What are coppers common valences?
Copper commonly exhibits two valences: +1 and +2. In the +1 oxidation state, it is known as cuprous copper, while in the +2 state, it is referred to as cupric copper. The +2 state is more stable and prevalent in compounds such as copper sulfate and copper chloride. Copper's ability to exist in multiple valences makes it versatile in various chemical reactions and applications.
