Configurations in 4d, 5d, etc. orbitals

[Anisha Chandra 1K]

So we discussed that chromium and copper have exceptions in that they become 3d54s1 and 3d104s1. Does this also happen to elements in the same group as these two, like in 4d, 5d, etc?

[KMenjivar_3A]

Yes, just remember that this technique is lonely allowed once the element is in 3d orbital or higher. Also, you should only use this rule for the d and s orbital.

Yes, elements in the same group will have the same exception because their electron configurations are similar in the amount of electrons and therefore have similar properties. Hope this helps!

When you have something with a 5d and 4s electron configuration, is the s orbital higher energy if there is an electron in the d orbital?
