Assertion : Hydrogen nuclei combines to form helium nuclei then...
Assertion : Hydrogen nuclei combines to form helium nuclei then energy is released.
Reason : Binding energy/nucleon of He is greater than hydrogen.
Options
- AIf both Assertion and Reason are true and Reason is the correct explanation of Assertion.
- BIf both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
- CIf Assertion is true but Reason is false.
- DIf Assertion is false but Reason is true.
Correct answer
A. If both Assertion and Reason are true and Reason is the correct explanation of Assertion.
Step-by-step solution
Anuclear reaction in which two lighter nuclei are fused together to form a heavier nuclei is called nuclear fusion. In such a process, more stable nuclei come into existence i.e., binding energy per nucleon increases. Fusionreactionsarehighlyexothermicbecause of loss of mass during fusion. e.g.
{ }_1^2 \mathrm{H}+{ }_1^2 \mathrm{H} \rightarrow{ }_2^4 24.9
