The maximum number of unpaired electrons in the 3d sublevel is 5. The maximum number of unpaired electrons in a single 3d orbital is 1.

Explanation:

There are 5 d orbitals in any d sublevel. Each orbital must have a single electron in each of the five orbitals before adding additional electrons. Therefore, the maximum number of unpaired electrons in the 3d sublevel is 5. The maximum number of unpaired electrons in a single 3d orbital is 1.
