JEE Main & Advanced Chemistry Structure of Atom Question Bank Quantum number, Electronic configuration and Shape of orbitals

  • question_answer If value of azimuthal quantum number \[l\] is 2, then total possible values of magnetic quantum number will be

    A)                 7             

    B)                 5

    C)                 3             

    D)                 2

    Correct Answer: B

    Solution :

               If value of l is 2 then \[m=-2,\,-1,\,0,\,+1,\,+2\]. \[m=-l\] to \[+l\] including zero. (5 values of magnetic quantum number)
