The electrons, identified by quantum numbers n and \(\text { I }\),

(i) n = 4, \(\text { I }\)  = 1, (ii) n = 4, \(\text { I }\)= 0, (iii) n = 3, \(\text { I }\) = 2, and (iv) n = 3, \(\text { I }\) = 1 can be placed in order of increasing energy, from the lowest to highest, as:

  1. (iv) < (ii) < (iii) < (i)
  2. (ii) < (iv) < (i) < (iii)
  3. (i) < (iii) < (ii) < (iv)
  4. (iii) < (i) < (iv) < (ii)

Answer

(B) (ii) < (iv) < (i) < (iii)
