A uranium nucleus (atomic number `92`, mass number `231`) emits an `alpha`-particle and the resultant nucleus emits a `beta`-particles. What are the atomic and mass numbers of the final nucleus? .

A

`90,233`

B

`90,238`

C

`91,238`

D

`93,238`

Text Solution

Verified by Experts

Simply, we can analyse from the equation,
`""_(92)U^(238)overset(-a)to""_(90)U^(234)overset(-beta)to""_(91)Y^(234)`
