Which one of the following particles is emitted as a result of the following nuclear reaction?Ra226 → Rn222
Correct answer: B. Alpha
- A. Beta
- B. Alpha
- C. Gamma rays
- D. One alpha and one beta
Explanation
Alpha particle has mass of 4 amu. And the mass number is reduced by 4 amu (from 226 to 222) hence indicating an alpha particle was emitted.
