A) A and C
B) \[_{92}{{U}^{235}}\]and C
C) A and B
D) A, B and C
Correct Answer: B
Solution :
\[_{92}{{U}^{235}}\xrightarrow{-\alpha }(A)\xrightarrow{-\beta }(B)\xrightarrow{-\beta }(C)\] (i) \[_{92-2}{{A}^{235-4}}{{=}_{90}}{{A}^{231}}\] (ii) \[_{90}{{A}^{231}}\xrightarrow{-\beta }{{\,}_{(90+1)}}{{B}^{(231)}}={{\,}_{91}}{{B}^{231}}\] (iii) \[_{91}{{B}^{231}}\xrightarrow{-\beta }{{\,}_{(91+1)}}{{C}^{231}}={{\,}_{92}}{{C}^{231}}\] Isotopes are \[_{92}{{U}^{235}}\] and CYou need to login to perform this action.
