Cu2+ is more stable than Cu+ even former have 3d9 configuration while later have 3d10 configuration.why?
Cu2+ is more stable than Cu+ due to higher hydration enthalpy of Cu2+ due to its small size and high charge as compared to Cu+
Sir/Madam
In the structure of copper sulphate(CuSO4.5H2o),4 water molecules are coordinated and 1 is hydrogen bonded. The electronic configuration of Cu is [Ar]4s1 3d10 . When the water molecules are sharing 8 electrons, it becomes 4s2 3d10 4p6 5s1. When cu becomes cu2+ion, the configuration becomes 4s2 3d10 4p5. But these 2 configurations aren't stable. Then why did cuso4.5h2o occurs at a reasonably good amount in nature. Kindly explain in "detail"?
