In which radioactive disintegration, neutron dissociates into proton and electron
$H{e^{ + + }}$ emission
$\beta - $emission
$\gamma - $emission
Positron emission
Which of the following will have highest penetrating power
${U^{238}}$ decays into $T{h^{234}}$ by the emission of an $\alpha - $ particle. There follows a chain of further radioactive decays, either by $\alpha - $ decay or by $\beta $ - decay. Eventually a stable nuclide is reached and after that, no further radioactive decay is possible. Which of the following stable nuclides is the and product of the ${U^{238}}$ radioactive decay chain
The radioactive decay of uranium into thorium is expressed by the equation $_{92}^{238}U \to _{90}^{234}Th + X,$ where $'X'$ is
In gamma ray emission from a nucleus
