Atomic Structure Question 496
Question: The following transition occurs when Lithium atoms are sprayed into hot flame. The various steps are numbered for identification.
$ 2s\xrightarrow{I}2p\xrightarrow{II}3d\xrightarrow{III}3p\xrightarrow{IV} $
$ 4s\xrightarrow{V}3p $ Which of these transitions result in emission of light-
Options:
A) I, II & V
B) III & V
C) III, IV & V
D) All
Show Answer
Answer:
Correct Answer: B
Solution:
- $ 2s\xrightarrow{I}2p\xrightarrow{II}3d\xrightarrow{III}3p\xrightarrow{IV}4s\xrightarrow{V}3p $ Energy of 3d is more than 3p therefore it will emit energy, similarly from $ 4s\to 3p $ transition.
