Nuclear Physics And Radioactivity Question 498
Question: A nucleus decays by $ {{\beta }^{+}} $ emission followed by a gamma emission. If the atomic and mass numbers of the parent nucleus are Z and A respectively, the corresponding numbers for the daughter nucleus are respectively.
Options:
A) $ Z-1 $ and $ A-1 $
B) $ Z+1 $ and $ A $
C) $ Z-1 $ and $ A $
D) $ Z+1 $ and
Show Answer
Answer:
Correct Answer: C
Solution:
[c] After $ {{\beta }^{+}}{(_{+1}}e^{0}) $ emission atomic number decreases by one and mass number remain unchanged. g-emission, there will be no change on mass number and atomic number.
