In the nuclear reaction, `{:(235),(92):}Urarr{:(207),(82):}` Pb, the number of `beta`- particles lost would be

A

`8,4`

B

`6,2`

C

`7,4`

D

`4,3`

Text Solution

Verified by Experts

The correct Answer is:
C
`""_(92)^(235)U to _(82)^(207)Pb+x_(2)^(4)alpha+y_(-1)^(0)beta`
`235=207+4ximpliesx=7`
`92=82+2x-y` or `y=4`
