A) 13
B) 52
C) 100
D) 73
Correct Answer: D
Solution :
By using the relation, \[r\propto {{A}^{1/3}}\] \[\frac{{{r}_{1}}}{{{r}_{2}}}={{\left( \frac{{{A}_{1}}}{{{A}_{2}}} \right)}^{1/3}}\] \[\frac{3}{5}={{\left( \frac{27}{A} \right)}^{1/3}}\] \[\frac{27}{125}=\frac{27}{A}\] \[A=125\] So, number of nuclei in atom \[X=A-52=125-52=73\]You need to login to perform this action.
