An atom has atomic mass 232 and atomic number 90. During the course of disintegration, it emits 2 `beta`-particles and few `alpha`-particles. The resultant atom has atomic mass 212 and atomic number 82. How many `alpha`-particles are emitted during this process?

Text Solution

AI Generated Solution

To solve the problem, we need to analyze the disintegration of the atom step by step. 1. **Identify the initial and final states of the atom:** - Initial atomic mass (A1) = 232 - Initial atomic number (Z1) = 90 - Final atomic mass (A2) = 212 - Final atomic number (Z2) = 82 ...

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.
