\({ }_{92} \mathrm{U}^{235}\) undergoes successive disintegrations with the end product of \({ }_{82} \mathrm{~Pb}^{203}\). The number of \(\alpha\) and \(\beta\) particles emitted are
- A \(\alpha=6, \beta=4\)
- B \(\alpha=6, \beta=0\)
- C \(\alpha=8, \beta=6\)
- D \(\alpha=3, \beta=3\)
Answer & Solution
Correct Answer
(C) \(\alpha=8, \beta=6\)
Step-by-step Solution
Detailed explanation
When an \(\alpha\) - particle emits from a radioactive nuclei, then its mass number is decreased by 4 unit and atomic number is decreased by 2 unit. When a \(\beta\)-particle emits from a radioactive nuclei, then its mass number is unaffected, whereas atomic number is increased…
