####56. If electron has spin quantum number $+1 / 2$ and a magnetic quantum number -1 , it cannot be present in
[1994]
(a) d-orbital
(b) f-orbital
(c) p-orbital
(d) s-orbital.
Show Answer
Solution:
- (d) For $s$-orbital; $l=0$
Thus value of $m$ must be zero, which is given as -1 in the question. Hence, the electron can not be present in $s$-orbital.
