7(ii)
(a) Complete the following radioactive reaction :
$_{-}^{-}\text X \rightarrow _{-}^{-}\text Y + _{2}^{4}\text {He} \rightarrow _{91}^{234}\text Z + _{-1}^{0}\text e$
(b) Uranium is available in two forms U-235 and U-238. Which of the two isotopes of Uranium is more fissionable?

(a) $_{92}^{238}\text X \rightarrow _{90}^{234}\text Y + _{2}^{4}\text {He} \rightarrow _{91}^{234}\text Z + _{-1}^{0}\text e$
(b) Comparatively speaking, U-235 is easier to fission than U-238 because only fast neutrons can cause the fission of U-238, whereas slow neutrons can even trigger the fission of U-235.
