`x_(1),x_(2),x_(3) and x_(4)` are particles/radiation emitted by the respective isotopes. The correct option(s) is (are):

A

`x_(1)` will deflect towards negatively charged plate.

B

`x_(2)" is "beta^(-)`

C

`x_(3)" is "gamma-ray`

D

Z is an isotope of uranium.

Text Solution

Verified by Experts

The correct Answer is:
A, B, D
The correct reactinn semnence is
`""_(92)^(238)U to ""_(90)^(234)Th +""_(2)^(4)He`
`""_(90)^(234)Th to ""_(91)^(234)Pa+""_(-1)^(0)e`
`""_(91)^(234)Pa to ""_(92)^(234)U+""_(-1)^(0)e`
`""_(92)^(234)U to ""_(90)^(230)Th +""_(2)^(4)He`
The positively charged `""_(2)^(4)He` muclei deflects towards negatively charged plate, `x_2, and x_3" are "beta` -particles, and Z is `""_(92)^(234)U.`
