s vs d orbital

Postby Nicole Garrido 2I » Fri Nov 02, 2018 5:06 pm

Why are some elements written with a d^10 rather than s^2 and d^8?

This situation usually happens with Zn 2+. Since we want to avoid having two half-filled orbitals when there are 2 electrons that could be used in the outer 4s shell, we take the electrons from s2 and give them to d8, so that this way the orbital is at fully filled with electrons (d10).

It is preferable for orbitals to be fully filled. We can do this by taking 2 electrons from s2 and give it to d8. This allows the d orbital to be fully filled and "happy".
