Question: A nucleus $ _{n}X^{m} $ emits one $ \alpha $ and one $ \beta $ particles. The resulting nucleus is [CBSE PMT 1998; BHU 2001; AFMC 2002]
Options:
A) $ _{n}{{X}^{m-4}} $
B) $ _{n-2}{{Y}^{m-4}} $
C) $ _{n-4}{{Z}^{m-4}} $
D) $ _{n-1}{{Z}^{m-4}} $
Show Answer
Answer:
Correct Answer: D
Solution:
$ _{n}X^{m} \xrightarrow{\alpha _{n-2}} X^{m-4} \xrightarrow{-\beta _{n-1}} X^{m-4} $
BETA
