`._(90)Th^(234)` disintegrates to give `._(82)Pb^(206)Pb` as the final product. How many alpha and beta particles are emitted during this process ?

Text Solution

Verified by Experts

Let `xalpha-` and `y beta-` particles are given out during the change.
`:. ` ` ._(90)Th^(234)rarr._(82)Pb^(206)+x._(2)He^(4)+y._(-1)e^(0)`
Equating mass number on both sides, ltbr. `234=206+4x+yxx0`
or `4x=234-206=28`
`:. X =(28)/(4)7` ltbr. Equating atomic number on both sides
`90=82+2x+y(-1)`
`=82+14+(-y)`
`y=96-90=6`
`:. ` Number of `alpha-` particles `=67`
and number of `beta-` particles`=6`
