3d or 4s higher energy
Solve any question of Structure of Atom with-. In fact the orbital energies depend on the existence of other electrons. Clarifying Electron Configurations Chemical Education Xchange For most transition metals its the latter that wins out. . Lower orbital energy but higher repulsion vs. Just as the area of a sphere increases when you increase its radius so too do the number of electrons increase as you increase the energy level. If two subshells or orbitals have the same nl value the subshell or orbital with lower n value will have lower energy. The oddity is the position of the 3d orbitals which are shown at a slightly higher level than the 4s. We know that the 4s electrons are lost first during ionization which means that they are of a higher energy level than the 3d orbital since the highest electrons are found farthest away from the nucleus thus are lost first during ionization.
