Which of the following statements are correct?

The mass defect of the nuclear reaction ${}_5\mathrm{B}^8{\to }_4{\mathrm{Be}}^8{+}_1{\mathrm{e}}^0$ is $\mathrm{\Delta m}$. The wrong expression is/are

The mass defect of the nuclear reaction ${}_5\mathrm{B}^8{\to }_4{\mathrm{Be}}^8{+}_1{\mathrm{e}}^0$ is $\mathrm{\Delta m}$. The wrong expression is/are

Mass of $1 \mathrm{amu}$ gives energy equal to

The nuclide lying below the stability belt in $\mathrm{n}-\mathrm{p}$ graph does not disintegrate by

A radioactive nuclide generally disintegrates by $\mathrm{\alpha }-$emission when its $\mathrm{N}/\mathrm{P}$ ratio is

The number of stable isotopes is the least when the number of neutrons and protons in the isotopes are, respectively,

The binding energy per nucleon of ${}^{16}\mathrm{O}$ is $7.97 \mathrm{MeV}$ and that of ${}^{17}\mathrm{O}$ is $7.75 \mathrm{MeV}$. The energy in $\mathrm{MeV}$ required to remove a neutron from ${}^{17}\mathrm{O}$ is

The average binding energy per nucleon(in $\mathrm{MeV}$) of ${}_{41}{}^{93}\mathrm{N}\mathrm{b}$ having mass $92.906376 \mathrm{u}$ is $n$. Write the value of $\left[n\right]$, where $\left[\right]$ denotes the greatest integer function.

(Given $m_p=1.0072796 \mathrm{u}$, $m_n=1.008665 \mathrm{u}$ and $1 \mathrm{u}=931 \mathrm{MeV}/c^2$ )

The question contains Statement 1 and Statement 2. Of the four choices given after the statements, choose the one that best describes the two statements.

Statement 1: Energy is released, when heavy nuclei undergo fission or light nuclei undergo fusion.
Statement 2: For heavy nuclei, the binding energy per nucleon increases with increasing $Z$, while for light nuclei, it decreases with increasing $Z$.

Following data is available about 3 nuclei P, Q & R. Their decreasing order of stability is given by

Assertion: Out of nuclei ${}_3{X}^7$ and ${{}_{3}Y}^4$ , former is likely to be more stable.

Reason: Size of ${}_3{X}^7$ is bigger than the size of ${{}_{3}Y}^4$
