Because in s block of Cu present one electron and in p block 11 electrons are present. If it loses two electron it become stable. Because of stability it doesn't release it doesn't show oxidation State more than 2

In an aqueous medium, Cu²⁺ is more stable than Cu⁺. This is because although energy is required to remove one electron from Cu⁺ to Cu²⁺, high hydration energy of Cu2+ compensates for it. Therefore, Cu⁺ ion in an aqueous solution is unstable.
