Quizplus · Accepted Answer

The magnetic quantum number, ml, specifies the orientation of the orbital in space and can take on integer values ranging from -l to +l. In a 5d subshell, l=2, which means that ml can take on the values -2, -1, 0, +1, or +2. Therefore, 3 is not a valid value for ml in a 5d subshell.
