Valency for copper
Answers
Answered by

Copper has two common valencies: +1 and +2.
- In its +1 oxidation state, copper forms compounds such as copper(I) oxide (Cu2O).
- In its +2 oxidation state, it forms compounds such as copper(II) oxide (CuO) and copper(II) sulfate (CuSO4).
These different valencies arise due to the loss of electrons from the outer electron shell of copper atoms in chemical reactions.
