In a radioactive decay chain, the initial nucleus is `overset(232)(90).^(Th)`. At the end there are 6 `alpha`-particles and 4 `beta`-particles which are emitted. If the end nucleus is `overset(A)(Z).^(X),A` and Z are given by :

A

A= 202 , Z = 80

B

A = 208 , Z = 80

C

A = 200 ,Z=81

D

A = 208 ,Z=82

Text Solution

Verified by Experts

The correct Answer is:
D
Change in `Z = (6xx2) - 4 = 8`
Change in `A = 6 xx 4 = 24`
`._(90)^(232)TH overset (6alpha) underset (4beta^(-))to ._(82)^(208) P_(B)`.
