NCERT Exercise 13.6 - Nuclei
Question: Suppose, we think of fission of a 56 26Fe nucleus into two equal fragments, 28 13 Al . Is the fission energetically possible? Argue by working out Q of the process. Given m ( 56 26Fe ) = 55.93494 u and m ( 28 13 Al ) = 27.98191 u.
Answer: **NCERT answer:** Q = ( ) ( ) 56 28 26 13 Fe – 2 Al m m = 26.90 MeV; not possible.
