Radon 86222Rn decays by α-and β-emission to Bismuth 83Bi214.For decay of each nucleus of Radon, how many α-and β-particles are emitted?
Correct answer: B. Option B
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
The Radon-222 decays by emitting 2 alpha particles and 1 beta particle. This decay occurs in a series of events which is represented by the equations given below:22286Rn → 21884Po + 42He21884Po → 21482Pb + 42He21482Pb → 21483Bi + 0-1e
