When .90 Th^228 transforms to .83 Bi^212...

When `._90 Th^228` transforms to `._83 Bi^212`, then the number of the emitted `alpha-`and `beta-`particle is, respectively.

A

`8 alpha, 7 beta`

B

`4 alpha, 7 beta`

C

`4 alpha, 4 beta`

D

`4 alpha, 1 beta`

Text Solution

Verified by Experts

The correct Answer is:
D
(d) `n_alpha = (228 - 212)/(4) = 4` and `n_(beta) = 2 xx 4 - 90 + 83 = 1`.

When an alpha -particle is emitted

Thorium isotope ._(90)Th^(232) emits some alpha -particle and some beta -particle and gets transformed into lead isotope ._(82)Pb^(200) . Find the number of alpha -and beta -particles emitted.

In a radioactive decay chain, ._(90)^(232)Th nucleus decays to ._(82)^(212)Pb nucleus. Let N_(alpha) and N_(beta) be the number of alpha and beta - particles, respectively, emitted in this decay process. Which of the following statements is (are) true ?

._(89)Ac^(231) after emission of some alpha and beta particles gives ._(82) Pb^(207) . The number of such alpha and beta - particles are respectively

._(n)X^(m) emitted one alpha and 2beta particles, then it will become :

._(90)Th^(232) to ._(82)Pb^(208) . The number of alpha and beta-"particles" emitted during the above reaction is

In the case of thorium (A = 232 and Z = 90) , we obtain an isotope of lead (A = 208 and Z = 82) after some radiactive disintegrations. The number of alpha and beta particle emitted are respectively.
