The number of `alpha` and `beta` -particle emitted in the transformation
`""_(92)^(238)U to ""_(92)^(234)U`

A

1,1

B

1,0

C

1,2

D

2,1

Text Solution

Verified by Experts

The correct Answer is:
C
`""_(92)^(238)U to ""_(92)^(238)U+x_(2)^(4)He+y""_(-1)^(0)e`
238=234+4x
`therefore x=1`
`92=92+2x-y`
y=2x=2
Therefore, 1 `alpha` -particle and `2-beta` -particles are emitted.

How many alpha and beta -particles are emitted in the transformation ""_(92)^(238)U rarr ""_(92)^(234)U

Calculate the number of alpha - and beta -particles emitted when ._(92)U^(238) into radioactive ._(82)Pb^(206) .

._(92)U^(238) is radioactive and it emits alpha and beta particles to form ._(82)Pb^(206). Calculate the number of alpha and beta particles emitted in this conversion. An ore of ._(92)U^(238) is found ot contain ._(92)U^(238) and _(82)Pb^(206) in the weight ratio of 1: 0.1. The half- life -period of ._(92)U^(238) is 4.5xx 10^(9) yr. Calculate the age of the ore.
