Question:
Out of the following pairs of electrons, identify the pairs of electrons present
in degenerate orbitals :
(i) (a) n = 3, l = 2, ml = –2, ms= − 1/2
(b) n = 3, l = 2, ml = –1, ms= − 1/2
(ii) (a) n = 3, l = 1, ml = 1, ms = +1/2
(b) n = 3, l = 2, ml = 1, ms = +1/2
(iii) (a) n = 4, l = 1, ml = 1, ms = +1/2
(b) n = 3, l = 2, ml = 1, ms = +1/2
(iv) (a) n = 3, l = 2, ml = +2, ms = − 1/2
(b) n = 3, l = 2, ml = +2, ms = +1/2
Solution:
Option (i) and (iv) are the answers.
