In successive emission of alpha and beta particles, how many alpha and beta particles should be emitted for the nautral (4n +1) series, conversion of ._(94)Pu^(241)" to" _(92)U^(233)

Answer»

`ALPHA, beta`
`alpha, 2beta`
`2alpha, 3 beta`
`2alpha, 2 beta`

Solution :`._(94)Pu^(241) rarr ._(92)U^(233) + x ._(2)He^(4) + y ._(-1)e^(0)`
`241 = 233 + 4x`
`x = 2`
`94 = 92 + 2 XX 2 - y`
`y = 2`
`2alpha and 2 beta` particles
