The difference between number of `alpha` and `beta` particles emitted during the conversion of `U_(92)^(238) to Pb_(82)^(206)` is

Text Solution

Verified by Experts

The correct Answer is:
2
`""_(92) U^(238) to ""_(82) Pb^(206) + a(""_(2) He^(4)) + b (""_(-1) beta^(0)) , 238 = 206 + 4a + 0`
`a = ((238 - 206)/(4)) = (32)/(4) = 8 alpha , 92= 82 + ( 8 xx 2) - b , b = 16 + 82 - 92 = 16 - 10 = 6 beta , (a - b) = 8 - 6 = 2 `
