The satble nucleus that has a radius half that of `Fe^(56)` is

A

`._(3)Li^(7)`

B

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

C

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

D

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

Text Solution

Verified by Experts

The correct Answer is:
A
Radius of `Os^(189)=r_(0)A_(os)^(1//3)`
Radius of that nucleus `=(1)/(3)xxr_(0)(A_(o_(5)))(1)/(3)=r_(0)((189)/(27))^(1)/(3)=r_(0)7^(1//3)`
`:. A` for that nucleus `=7`
