A solid $A B$ has the NaCl structure. If radius of cation $A^{+}$ is 120 pm , the maximum possible value of the radius of the anion $B^{-}$ is

Options:

Answer:

Solution:

For NaCl crystal, Radius of cation/radius of anion $= 0.414$ $\frac{r _{A^{+}}}{r _{B^{-}}} = 0.414 r_{B^{-}} = \frac{r _{A^{+}}}{0.414} = \frac{120}{0.414} = 290 pm$
