How may `alpha-` and `beta-` particles will be emitted when `._(90)Th^(232)` changes into `._(82)Pb^(208)`?

A

8,6

B

6,4

C

,4,2

D

2,2

Text Solution

Verified by Experts

The correct Answer is:
B
`""_(90)Th^(232) to ""_(82)Pb^(208)Pb + x_(2)He^(4)+ y ""_(-1)^(0)e`
`232=208 + 4x`
`x=(24)/(4)=6`
`90=82+ 2x -y`
`y=82 + 12 - 90`
y=4
