    If magnetic quantum number of a given atom is represented by -3, then what will be its principal quantum number?

    A)  2                                            

    B)  3

    C)  4                                            

    D)  5

    Correct Answer: C

    Solution :

                     If the highest value of magnetic quantum Number\[=-3\]then,\[l=3\] (\[\because \]m has value from -1 to o,\[+l\]) \[\therefore \]\[n=4\]        (\[\because \]I has values form 0 to\[n-1\])
