The molecular formula of copper(II) sulfate is CuSO4. Its chemical name is cupric sulphate. Copper has two oxidation states of +2 and +1. In CuSO4, the copper ion has oxidation state +2.
When copper forms a compound with the oxidation state +1, its molecular formula is different. The atomic number of copper is 29 and its electron configuration is 1s22s2 2p63s2 3p6 3d104s1 or 2, 8, 18, 1 electrons per shell. The electrons in the 3d104s1 are involved in bond formation, so copper has two oxidation states. Copper is a good conductor of electricity and melts at 1984.32 degrees Fahrenheit.
