If $M$ is the atomic mass and $A$ is the mass number,the packing fraction is given by

What is nuclear energy? Explain how nuclear energy is released from the curve of binding energy.

The mass of the oxygen isotope $_8O^{17}$ is $M_0$. If $M_p$ and $M_n$ are the masses of a proton and a neutron respectively,the nuclear binding energy of the isotope is ......

Assertion : Binding energy (or mass defect) of hydrogen nucleus is zero.
Reason : Hydrogen nucleus contains only one nucleon.

The curve of binding energy per nucleon as a function of atomic mass number has a sharp peak for the helium nucleus. This implies that helium

If the binding energy per nucleon in $Li^7$ and $He^4$ nuclei are respectively $5.60 \ MeV$ and $7.06 \ MeV$, then the energy of the reaction $Li^7 + p \to 2He^4$ is ......... $MeV$.
