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

  • question_answer The correct order of increasing energy of atomic orbitals is [MP PET 2002]

    A)                 \[5p<4f<6s<5d\]             

    B)                 \[5p<6s<4f<5d\]

    C)                 \[4f<5p<5d<6s\]             

    D)                 \[5p<5d<4f<6s\]

    Correct Answer: B

    Solution :

               According to Aufbau principle electron are filled in various atomic orbital in the increasing order of  energy 1s < 2s < 2p < 3s < 3p < 4s < 3d < 4p < 5s < 4d < 5p < 6s < 4f < 5d < 6p < 7s.
