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