If it is assumed that \({ }_{92}^{235} U\) decays only by emitting \(\alpha\) and \(\beta\) particles, the possible product of the decay is :
- A \({ }_{89}^{225} A c\)
- B \({ }_{89}^{227} A c\)
- C \({ }_{89}^{230} A c\)
- D \({ }_{89}^{231} A c\)
Answer & Solution
Correct Answer
(B) \({ }_{89}^{227} A c\)
Step-by-step Solution
Detailed explanation
New mass no. \(=235-2 \times 4=227\) New at. no. \(=92-2 \times 2+1=92-4+1=89\)
