Illustrate and describe the sequence in which ten electrons occupy the five orbitals related to an atoms d sublevel

Actually a d sublevel contains 5 orbitals. So in this case, the electrons would first fill each of the five orbitals so remaining electrons are 5. Now this remaining 5 electrons would pair with the filled orbital. That is, the 6th electron would pair its spin with the 1st orbital, the 7th electron would pair with the one in the 2nd orbital, and so on.
