Correct Answer: C
Solution :
\[NaCl\] has fee structure. In fee lattice \[{{r}^{+}}+{{r}^{-}}=\frac{a}{2}\] where a = edge length \[{{r}^{+}}=95\,pm\,\,\,{{r}^{-}}=181\,pm\] Edge length \[=2{{r}^{+}}+2{{r}^{-}}\] \[=(2\times 95+2\times 181)\,pm\] = 190 + 362 = 552 pmYou need to login to perform this action.
