In the transformation of `""_(92)""^(238)U` to `""_(92)""^(234)U`, if one emission is an `alpha` particle, what should be the other emission(s)? a)Two `beta""^(-)`Two `beta""^(-)` b)Two `beta""^(-)` and one `beta""^(-)` c) One `beta""^(-)` and one `gamma` d)One `beta""^(+)` and one `beta""^(-)`

Options

A. Two` beta^-`
B. Two `beta^(-) and one beta^+`
C. One `beta^(-)` and one `gamma`
D. one `beta^(+) and one beta^-`

Answer

A

Explanation

`""_(92)^(238)U underset("emission")overset(1 alpha "Particle")to ""_(90)^(234)Th underset("emission")overset(2beta "Particles")to ""_(92)^(234)U`
