    If the principal quantum number n = 6, the correct sequence of filling of electrons will be:

    A) \[ns\to (n-2)f\to np\to (n-1)d\]

    B) \[ns\to (n-2)f\to (n-1)d\to np\]

    C) \[ns\to np\to (n-1)d\to (n-2)f\]

    D)  \[ns\to (n-1)d\to (n-2)f\to np\]

    Correct Answer: B

    Solution :

    [b] The sequence of filling electrons in sixth period: \[6s-4f-5d-6p\] i.e., \[(ns)\to (n-2)f\to (n-1)d\to np\]
