S and D Oribitals

Postby Diana A 2L » Sun Oct 27, 2019 11:50 pm

Why is it that with some atoms with electrons in the D-orbitals, the S-orbitals will have more energy than the D-orbitals. For example, why would a 4s1 electorn have more energy than a 3d5 electron?

The half filling or ful filling (5 or 10 electrons) of 3d orbital is a lower energy state for the electrons to be in, with 4s having 1 electron, than 4s2 and 3d4 or 3d9. see here for explanation: https://chemistry.stackexchange.com/que ... %20orbital.
