Question

The electrons identified by quantum numbers n and l, are as follows
(I) n = 4, l = 1
(II) n = 4, l = 0
(III) n = 3, l = 2
(IV) n = 3, l = 1
If we arrange them in order of increasing energy, i.e. from lowest to highest, the correct order is

• A. IV < II < III < I
• B. II < IV < I < III
• C. I < III < II < IV
• D. III < I < IV < II

Answer 1

The Correct Option is A

The correct option is (A): IV < II < III < I.
