Question 552: Atoms & Nuclei

Question

A nucleus with mass number 240 breaks into two fragments each of mass number 120, the binding per nucleon of unfragmented nuclei is 7.6MeV while that of fragments is 8.5MeV. The total gain in the Binding Energy in the process is :

Accepted Answer

Given binding energy per nucleon of X, Y & Z are
7.6MeV, 8.5MeV & 8.5MeV respectively,
Gain in binding energy is :
Q = Binding Energy of products $$-$$ Binding energy of reactants
= (120 $$	imes$$ 8.5 $$	imes$$ 2) $$-$$ (240 $$	imes$$ 7.6) MeV
= 216 MeV

Answer

216MeV

Answer

0.9MeV

Answer

9.4MeV

Answer

804MeV
