In the disintegration series
`._(92)^(238)U overset rarr (alpha) X overset rarr (beta^(-))._Z^(A)Y` the values of `Z` and `A`, respectively, will be

A

`92326`

B

`88230`

C

`90234`

D

`91234`

Text Solution

Verified by Experts

The correct Answer is:
d
`alpha`-decay decreases mass number by `4` and reduces charge number by `2`. `beta`-deacy keeps mass number unchanged and increases charege by `1`. clearly, option (d) is the right choice .
