Q. For which one of the following sets of four quantum numbers, an electron will have the heighest energy?
Structure of Atom
A
$n- 3 ,l - 2 ,m- 1 ,s - 1/2$
7%
B
$ n- 4 ,l - 2 ,m- -1 ,s -1/2$
73%
C
$ n- 4 ,l - 1 ,m- 0 ,s - (-1/2)$
3%
D
$n- 5 ,l - 0 ,m- 0 ,s -(-1/2)$
17%
Solution:
The sub-shell are $3 d, 4 d, 4 p$ and $4 s, 4 d$ has highest energy as $n+\ell$ value is maximum for this.
