Among the following subshells, 3d, 4s, 4p, 4d, 4f, 5s, 5p, 5d, 5f, and 6s, which can have a magnetic quantum number m_l = 2?

Among the following subshells, 3d, 4s, 4p, 4d, 4f, 5s, 5p, 5d, 5f, and 6s, which is/are described by the angular momentum quantum number l = 1?

Mercury exists in nature as Hg, Hg⁺, and Hg²⁺. Mercury loses an electron when it goes from Hg⁺ to Hg²⁺. Give the n and l quantum numbers of the electron lost from this transition.

Using the aufbau principle, predict the principal quantum number (n) and angular momentum quantum number (l) for the subshell that should be filled after the 4p subshell?
