In the disintegration of a radioactive element, `alpha`- and `beta`-particles are evolved from the nucleus. `._(0)n^(1) rarr ._(1)H^(1) + ._(-1)e^(0) +` Antineutrino + Energy `4 ._(1)H^(1) rarr ._(2)He^(4) + 2 ._(+1)e^(0) +` Energy Then, emission of these particles changes the nuclear configuration and results into a daughter nuclide. Emission of an `alpha`-particles results into a daughter element having atomic number lowered by 2 and mass number by 4, on the other hand, emission of a `beta`-particle yields an element having atomic number raised by 1. Which of the following combinations give finally an isotope of the parent element?a)alpha, alpha, beta`b)`alpha, gamma, alpha`c)`alpha, beta, beta`d)`beta, gamma, alpha`A. `alpha, alpha, beta`B. `alpha, gamma, alpha`C. `alpha, beta, beta`D. `beta, gamma, alpha` |
