Consider the following statements and state whether true() or false():
(i) Nuclear fission is normally followed by emission of particles.
(ii) Emission of particle is normally followed by emission of rays
(iii) As the mass number A increases, the binding energy per nucleon in a nucleus also increases
Choose the correct order from the options given below.
Options:
Answer:
Solution:
(i) Nuclear fission results in fragments whose neutron/proton ratio is higher than the required value (N/P ratios is greater for heavier nuclei). To reduce the N/P ratio these fragments undergo decays in which a neutron is converted into a proton.
(ii) Some of the energy generated in emission goes into nuclear excitation. The excited nucleus returns to ground state by emission.
(iii) the binding energy per nucleon in a nucleus varies in a way that depends on the actual value of
