In the transformation of ""_(92)^(238)U to ""_(92)^(234)U, if one emission is an alpha-particle, what should be the other emission ?

Answer»

Two `beta^(-)` and one `beta^(+)`
One `beta^(-)` and one `gamma`
One `beta^(+)` and one `beta^(-)`
Two `beta^(-)`

SOLUTION :`""_(92)^(238)UTO""_(92)^(234)U+""_(2)^(4)He+2overset(0)-1^(E)`
i.e., `2beta^(-)`
