Question
The ore of Uranium found in nature contain `""_92U^218` and `""_92U^235`. Although both the isotopes are fissionable. It is found out experimentally that one of the two isotopes is more easily fissionable.
1) Name the isotope of Uranium which is easily fissionable.
2) Give a reason for your answer.
3) Write a nuclear reaction when Uranium 238 emits an alpha particle to form a Thorium (Th) nucleus
Solution
1) `""^235U`
2) `""_92^235U` is less stable than `""_92^238U`
3) `""_92^238U-> ""_90^234Th + ""_2^4He`
