In successive emission of `beta` and `alpha` -particles, how many `alpha` and `beta` -particles should be emitted for the natural (4n+1 series) conversion of `""_(94)^(241)Pu` to `""_(92)^(233)U` are

A

`alpha, beta`

B

`alpha, 2beta`

C

`2 alpha, 3 beta`

D

`2 alpha , 2 beta`

Text Solution

Verified by Experts

The correct Answer is:
D
`""_(94)^(241)Pu to ""_(92)^(233)U + ""_(2)^(4)He + y""_(-1)e^(0)`
241=233=4x
4x=8
x=2
`94=92 + 2 xx 2 -y`
y=2
`therefore 2 alpha` and 2 `beta`-particles are emitted.
