Question 16: NCERT Solutions for 12th Class Physics: Chapter 13-Nuclei
Suppose, we think of fission of a
nucleus into two equal fragments,
. IS the fission energetically possible? Argue by working out Q of the process.
Given,
= 55.93494 u
and
= 27.98191 u.
Solution:

The fission of Fe-56 into two fragments of
As the Q-value is negative, the fission is not possible energycally.
