What is the number of atoms per unit cell in a body-centered cubic $(BCC)$ unit cell?

If the radius of an anion is double that of a cation,the coordination number of the cation and the type of hole occupied are respectively:

For an ionic crystal with the general formula $AX$,the coordination number is $6$. What is the radius ratio range?

The solid $AB$ has a $NaCl$ type structure. If the radius of the $A^{+}$ ion is $120 \, pm$, then the maximum radius of the $B^{-}$ ion will be ........... $pm$.
