Question:
The stability of \(Cu^{2+}\) is more than \(Cu^+\) salts in aqueous solution due to
The stability of \(Cu^{2+}\) is more than \(Cu^+\) salts in aqueous solution due to
Updated On: May 12, 2024
- Enthalpy of atomization
- Hydration energy
- Second ionisation enthalpy
- First ionisation enthalpy
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
\(Cu_{(s)} \to Cu_{(g)} \to Cu_{(g)}^+ \to Cu_{(g)}^{2+} \to Cu_{(aq)}^{2+}\)
Because \(Cu^{2+}\) releases more hydration energy than \(Cu^+\), it is more stable than the latter.
Therefore, The correct option is (B): Hydration energy
Because \(Cu^{2+}\) releases more hydration energy than \(Cu^+\), it is more stable than the latter.
Therefore, The correct option is (B): Hydration energy

P-Block Elements
- P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons, therefore in all there are six groups of p-block elements.
- P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron. You will find some amazing properties of elements in a P-block element like gallium. It’s a metal that can melt in the palm of your hand. Silicon is also one of the most important metalloids of the p-block group as it is an important component of glass.
P block elements consist of:
- Group 13 Elements: Boron family
- Group 14 Elements: Carbon family
- Group 15 Elements: Nitrogen family
- Group 16 Elements: Oxygen family
- Group 17 Elements: Fluorine family
- Group 18 Elements: Neon family
