    The two electrons have the following sets of quantum numbers: \[P=3,2,-2,+\frac{1}{2},\,\,Q=3,\,0,\,0,+\frac{1}{2}\] Which of the following statements is true?

    A)  P has greater energy than Q.

    B)  P and Q represent same electron.

    C)  P and Q have same energy.

    D)  P has lesser energy than Q.

    Correct Answer: A

    Solution :

    : From the given quantum numbers, it can be inferred that: P electron belongs to 3d orbital. Q electron belongs to 3s orbital. Hence, P has greater energy than Q.
