The given quantum numbers ( n = 4 ) and ( l = 2 ) correspond to an electron in a 4d subshell. Here, ( n ) represents the principal quantum number, indicating the energy level, while ( l ) represents the angular momentum quantum number, corresponding to a d-orbital (since ( l = 2 ) for d). The possible magnetic quantum numbers ( m_l ) for ( l = 2 ) are -2, -1, 0, 1, and 2, indicating the various orientations of the orbital. Thus, any electron in the 4d subshell could have these quantum numbers, but you would need to specify ( m_l ) and the spin quantum number ( m_s ) to fully define the electron's state.
