Help needed in chemistry

Why $Cu^{2+}$ is most stable,though $Cu^{+}$ has a fullfilled $d$ -orbital.

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

In this case hydration enthalpy comes into picture,since we are taking about aqueous solutions $Cu^{2+}$ has higher hydration enthalpy than $Cu^{+}$ because of its small size and higher charge.

what is hydration enthalpy?can you pls explain...

In aqueous solution, ${ Cu }^{ + }$ disintegrates into ${ Cu }^{ 2+ }$ and Cu. Well , I hope you may have asked the question after coming across this phenomenon, isn't it @Souryajit Roy ?

Basically,i didnt know this before....I got this question while doing periodic table......

See@Souryajit Roy This is an example of disproportion reaction .As mentioned by@Krishna Sharma HYDRATION ENTHALPY comes into effect.
