     Which of the following are suitable for the fusion process?
 

 Nuclear fusion is possible :

A nucleus represented by the symbol ${}_Z{}^{A}X$ has

In the reaction ${}_1{}^2\mathrm{H}+{}_1{}^3\mathrm{H}\to {}_2{}^4\mathrm{He}+{}_0{}^1\mathrm{n}·$ If the binding energies of ${}_1{}^2\mathrm{H},{}_1{}^3\mathrm{H}$  and  ${}_2{}^4\mathrm{He}$ are respectively $a, b\text{ and} c (\text{in} \mathrm{MeV})$, then the energy (in $\mathrm{MeV}$) released in this reaction is

Fission of nuclei is possible, because the binding energy per nucleon in them
 

A radioactive reaction is ${}_{92}{U}^{238}{\to }_{82}P{b}^{206}$. How many $\alpha and \beta$ particles are emitted ?

When ₉₀Th²³⁸ changes into ₈₃Bi²²², then the number of emitted $\alpha and \beta$-particles are

A radioactive nucleus decay as follows. 

$X\stackrel{\alpha }{\to } X_1\stackrel{\beta }{\to }{X}_2\stackrel{\alpha }{\to } X_3\stackrel{\gamma }{\to } X_4,$
if the atomic number and the mass number of $X \text{are }72 \text{and }180$ then the mass number and atomic number of $X_4$ are
