    B. The principal quantum number (n) is 6, the angular momentum quantum number (ell) is 2, and there are 5 electrons in the subshell.

    Explanation:

    Given;

    electronic configuration of 6d⁵

    where;

    6 in the configuration shows that, the principal quantum number (n) is 6

    d is the subshell

    d orbital has angular momentum quantum number (l) of 2

    s orbital, l = 0

    p orbital, l = 1

    d orbital, l = 2

    f orbital, l = 3

    5 in the configuration means that there are 5 electrons in the subshell

    Therefore, 6d⁵ symbol means that "The principal quantum number (n) is 6, the angular momentum quantum number (ell) is 2, and there are 5 electrons in the subshell".
