A) 52
B) 73
C) 125
D) 13
Correct Answer: B
Solution :
\[r\propto {{A}^{1/3}}\] Þ \[\frac{{{r}_{1}}}{{{r}_{2}}}={{\left( \frac{{{A}_{1}}}{{{A}_{2}}} \right)}^{1/3}}\] Þ \[\frac{3}{5}={{\left( \frac{27}{A} \right)}^{1/3}}\]Þ \[\frac{27}{125}=\frac{27}{A}\]Þ \[A=125\] Number of nuclei in atom X \[=A-52=125-52=73.\]You need to login to perform this action.
