In the radioactive decay, ""_(92)X^(232) to ""_(89)Y^(20) , how many alpha and beta particles are ejected from X to from Y ?

Answer»

`3 ALPHA and 3 beta`
`5 alpha and 3 beta`
`3 alpha and 5 beta`
`5 alpha and 5 beta`

SOLUTION :`""_(92)^(232)X to ""_(89)^(220)Y, alpha = (232 - 220)//4 = 3`
`beta = 89 - (92 - 3 xx 2) = 3`
