QUESTION:-

Which stable nucleus has radius half than that of Fe56?

ANSWER:-

• Lithium (v||) or (Li 7) has a radius half that of Fe56

EXPLANATION:-

The Relation between nuclei Radius (R) and Mass number (A) is given by

R is directly proportional to A⅓

or A is directly proportional to R³

$= \frac{A1}{A2} = ({ \frac{R1}{R2} })^{3}$

Given:-

• R1 = R
• $R2 = \frac{R}{2}$
• A = 56

$\frac{56}{A2} = ( { \frac{R}{ \frac{R}{2} } })^{3} \\ A2 = \frac{56}{8} \\ A2 = 7$

Hence, the element with mass number 7 which is Lithium (Li 7) has a nucleus that has a radius half that of Fe 57.
