Vedclass · Answer

(C) The nuclear radius $R$ is given by the formula $R = R_0 A^{1/3}$,where $A$ is the mass number and $R_0$ is a constant.Therefore,the ratio of the radii is given by $\frac{R_{Au}}{R_{Ag}} = \left( \frac{A_{Au}}{A_{Ag}} \right)^{1/3}$.Given $A_{Au} = 197$ and $A_{Ag} = 107$,we have:$\frac{R_{Au}}{R_{Ag}} = \left( \frac{197}{107} \right)^{1/3}$.Calculating the value: $\frac{197}{107} \approx 1.841$.Then,$(1.841)^{1/3} \approx 1.2256$.Rounding to two decimal places,we get $1.23$.

The ratio of the nuclear radii of the gold isotope ${}_{79}^{197}Au$ and the silver isotope ${}_{47}^{107}Ag$ is $ . . . . . . $.
