Structure of Atom

Match List I with List II.

List I (Quantum number) List II (Information provided)
A. mlm_l I. Shape of orbital
B. msm_s II. Size of orbital
C. ll III. Orientation of orbital
D. nn IV. Orientation of spin of electron

Choose the correct answer from the options given below:

  1. A.A-III, B-IV, C-I, D-II✓
  2. B.A-III, B-IV, C-II, D-I
  3. C.A-II, B-I, C-IV, D-III
  4. D.A-I, B-III, C-II, D-IV

Solution

nn fixes orbital size (II), ll its shape (I), mlm_l its orientation (III), and msm_s the spin orientation of the electron (IV). Hence A-III, B-IV, C-I, D-II.
