JEE Main & Advanced Chemistry Structure of Atom / परमाणु संरचना Sample Paper Topic Test - Structure of Atom

  • question_answer
    What is the maximum number of electrons in an atom that can have quantum numbers \[n=4\,{{m}_{e}}=+1\]

    A)  4

    B) 15       

    C)

    D) 6

    Correct Answer: D

    Solution :

    [d] \[n=4\ell =0\]            \[{{m}_{e}}=0\]
    \[\ell =2;\,\,\,\,{{m}_{e}}=-1,\,\,\,\,0+1\]
    \[\ell =2;\,\,\,{{m}_{e}}=-2,\,\,\,-1,\,\,\,0+1,\,\,+2\]
    \[\ell =3;\,\,\,{{m}_{e}}=-3,\,\,-2,\,\,-1,\,\,0+1,\,\,+2+3\]
    There are three orbitals having \[{{m}_{e}}=+1\] thus maximum number of electrons in them will be 6.
