For the decay of nucleus, the possible reason which is not true
Neutron proton ratio too high
Neutron proton ratio too low
Size of nucleus very large
Binding energy of nucleus is more than that of its products
The nuclear force between two nucleons is explained by
Explain by illustrating the types of atoms.
Size of nucleus is of the order of
Assertion : The binding energy per nucleon, for nuclei with atomic mass number $A > 100$, decreases with $A$.
Reason : The nuclear forces are weak for heavier nuclei.
Nucleus of an atom whose atomic mass is $24$ consists of
