1.

The number of alphaand beta- particles emitted, when the following nuclear transformation takes place are _______ and __________ respectively.{:(238),(92):} X rarr{:(206),(82):} Y

Answer»


SOLUTION :`._(92)^(238)X rarr. _(82)^(206)Y + x alpha + y alpha`
`._(92)^(238)X rarr ._(82)^(206) Y + x(._(2)\He^(4))+y(._(-1)^(0)e)`
COMPARING mass no.
`238 rArr 206 + 4X +0y`
`x=8 i.e. 8 (alpha) `particles
Comparing no. protons.
92=82 + 2x-y
`10=2 xx 8 -y`
`y=6 i.e. 6 (beta)` particle
