Chemistry Question on Quantum Mechanical Model of Atom
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
IV < II < III < I
Explanation
Solution
The correct option is (A): IV < II < III < I.
