Introducing a second electron into a 3d orbital produces more repulsion than if the next electron went into the 4s orbital. There isn't a very big gap between the energies of the 3d and 4s orbitals.

Shielding of electron and energy difference in different orbitals. rocktown1990 Thu, 10/13/2011 - 12:01. How does electron shielding in multielectron atoms give rise to energy different among 3s, 3p, and 3d orbitals? Because the average distance from the nucleus of these orbitals is different so 3s will shield 3p and 3d, while 3p will shield 3d so extra screening ---my teacher said this explanation was good , but I needed to add something about the mole to it---- can someone please help.

Scandium will be the first element to fill an electron in 3d sublevel since it has 21 electrons.

The reduction in repulsion more than compensates for the energy needed to do this. Ans: Once 3d orbitals are occupied by electrons, like in the case of transition elements, because they are closer to the nucleus, they will repel the 4s electrons further away from the nucleus and cause it to have higher energy level.
