Atomic Structure Question 192
Question: What are the values of the orbital angular momentum of an electron in the orbitals Is, 3s, 3d and 2p-
Options:
A) $ 0,,0,,\frac{h}{2\pi }\sqrt{6},\frac{h}{2\pi }\sqrt{2} $
B) $ 1,,1,,\frac{h}{2\pi }\sqrt{4},\frac{h}{2\pi }\sqrt{2} $
C) $ 0,,1,,\frac{h}{2\pi }\sqrt{4},\frac{h}{2\pi }\sqrt{3} $
D) $ 0,,0,,\frac{h}{2\pi }\sqrt{20},\frac{h}{2\pi }\sqrt{6} $
Show Answer
Answer:
Correct Answer: A
Solution:
- From $ \sqrt{\ell (\ell +1)}\frac{h}{2\pi } $ Values of 1 for 1s, 2s, 3d, and 2p are 0,0,2,1. $ 0,0,\frac{h}{2\pi }\sqrt{6},\frac{h}{2\pi }\sqrt{2} $
