Staements I: ._zX^4 undergoes 2 alpha -decays, 2 beta -decays (negative beta ) and 2 gamma -decays. As a result, the daughter product is ._z-2X^(A-B) . Staements II: In beta -decay, the mass number decreases by 4 unit and atomic number decreases by 2 unit. In beta -decay (negative beta ), the mass number remains unchanged and atomic number increases by 1 unit. In gamma -decay, mass number and atomic number remain unchanged.

Which of the following causes the emission of X -rays? a. Electron capture b. gamma -emission c. alpha - emission d. beta -emission

In the gamma decay of a nucleus

U^238 decays into Th^234 by the emission of an a-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 end product of the U^238 radioactive decay chain ?
