Question

3d¹⁰ 4s² and 3d¹⁰ 4s⁰ which one is more stable and why.​

Answer 1

There is a general trend that half filled and completely filled orbitals are more stable than incompletely filled orbitals

There is a general trend that half filled and completely filled orbitals are more stable than incompletely filled orbitalsCu(II) is more stable than Cu(I) because it has a 2+ charge and is smaller than Cu(I).

There is a general trend that half filled and completely filled orbitals are more stable than incompletely filled orbitalsCu(II) is more stable than Cu(I) because it has a 2+ charge and is smaller than Cu(I). The electron density and effective nuclear charge is greater for Cu(II) and it forms stronger bonds(high hydration energy) and releases more energy and is more stable.
