Quizplus · Accepted Answer

The set of quantum numbers given in choice D violates the principle that the magnetic quantum number (ml) cannot exceed the principal quantum number (n) minus 1. In this case, ml has a value of 6, which exceeds the maximum value allowed for n=5. This is not allowed. All other choices have allowed quantum number sets.
