Nuclear Physics And Radioactivity Question 325
Question: An element A decays into element C by a two-step process : $ A\to B+{\ _{2}}He^{4} $ $ B\to C+\ 2{{e}^{-}} $ Then [CBSE PMT 1994; AMU 2002; KCET 2003]
Options:
A) A and C are isotopes
B) A and C are isobars
C) A and B are isotopes
D) A and B are isobars
Show Answer
Answer:
Correct Answer: A
Solution:
$ \alpha $ decay decreases the mass number by 4 and atomic number by 2, $ \beta $ decay increases the atomic number by 1. Here atomic number of C is same as that of A.
