The stable nucleus that has a radius `1//3` that of `Os^(189)` is-

A

`""_(3)Li^(2)`

B

`""_(2)He^(4)`

C

`""_(5)B^(10)`

D

`""_(6)C^(12)`

Text Solution

Verified by Experts

Radius of `Os^(189)=r_(0)A_(Os)^(1//3)`
Radius of that nucleus `=1/3xxr_(0)(A_(Os))^(1/3)=r_(0)(189/27)^(1/3)=r_(0)7^(1//3)`
`:.` A for that nucleus =7
