In the transformation of ._(92)^(235)U " to " ._(92)^(234)U, if one emission is an alpha-particle, what should be the other emission (s)

Answer»

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

Solution :`._(92)^(238)U underset("emission")overset(1 alpha "Particle")rarr ._(92)^(234)Th underset("emission")overset2 beta ("PARTICLES")rarr ._(92)^(234)U`
