To solve this problem, we need to understand the significance of each quantum number in atomic physics.$\\$List I contains quantum numbers, and List II contains their corresponding properties. Let's analyze each:$\\$• $m_l$ (magnetic quantum number): This quantum number is related to the orientation of the orbital in space.$\\$• $m_s$ (spin quantum number): This quantum number describes the orientation of the spin of an electron.$\\$• $l$ (azimuthal quantum number): This quantum number determines the shape of the orbital.$\\$• $n$ (principal quantum number): This quantum number is related to the size of the orbital.$\\$Now, let's match List I with List II:$\\$A. $m_l \rightarrow$III. Orientation of orbital$\\$B. $m_s \rightarrow$IV. Orientation of spin of electron$\\$C. $l \rightarrow$I. Shape of orbital$\\$D. $n \rightarrow$II. Size of orbital$\\$Therefore, the correct matching is:$\\$A->III, B->IV, C->I, D->II$\\$This corresponds to Option 4.
