The first controlled artificial disintegration of an atomic nucleus was achieved by

In the nuclear reaction $_{92}U^{238} \to _{82}Pb^{206} + x\,_{2}He^{4} + y\,_{-1}\beta^{0}$,the values of $x$ and $y$ are respectively......

If $_{92}U^{235}$ nucleus absorbs a neutron and disintegrates into $_{54}Xe^{139}$,$_{38}Sr^{94}$ and $X$,then what will be the product $X$?

An artificial radioactive isotope gave $_7^{14}N$ after two successive $\beta$-particle emissions. The number of neutrons in the parent nucleus must be

$_1H^2 + _1H^2 \to _2He^3 + _0n^1$. The above nuclear reaction is called:

$_6C^{12}$ and $_1T^3$ are formed in nature due to the nuclear reaction of a neutron with:
