10. _____ T or F A set of quantum numbers can be repeated within the same atom.
10. Label each of the following sets of four quantum numbers as either Valid, which indicates that set is a
legitimate set of quantum numbers for an electron, or Invalid, which would indicate that the set is not
a possible set of quantum numbers for an electron. (Hint: Check them with the rules on the quantum
numbers in the notes)
