Question
Match List I with List II
| List I (Quantum Number) | List II (Information provided) |
|---|---|
| A. mₗ | I. Shape of orbital |
| B. mₛ | II. Size of orbital |
| C. ℓ | III. Orientation of orbital |
| D. $n$ | IV. Orientation of spin of electron |
Choose the correct answer from the options given below:
Options
A.A-III, B-IV, C-II, D-I
B.A-II, B-I, C-IV, D-III
C.A-I, B-III, C-II, D-IV
D.A-III, B-IV, C-I, D-II
Solution
Sol. [Key Concept: Information given by quantum numbers]
The magnetic quantum number mₗ specifies orbital orientation (A–III). The spin quantum number mₛ specifies the electron spin projection (B–IV). The azimuthal quantum number ℓ specifies the subshell and orbital shape (C–I). The principal quantum number n specifies the principal shell and is associated with orbital size (D–II). Hence, option (4).
