A) \[^{232}U\]
B) \[^{232}Pa\]
C) \[^{230}Th\]
D) \[^{230}Ra\]
Correct Answer: D
Solution :
Alpha particle has mass number 4 and atomic number 2. Therefore, after emission of an alpha particle. The mass number of the \[^{234}U\] will reduce by 4 and after decay it becomes \[^{230}Ra\].You need to login to perform this action.
