$A$ cubic lattice has $A$ atoms at the body centre,$B$ atoms at the corners,and $C$ atoms at half of the face centres. The formula of the lattice is:

In a compound formed by $A^{+}$ and $B^{-}$ ions,$B^{-}$ ions are arranged at all corners except two and at all face centers except three,while $A^{+}$ ions are at the midpoints of all body diagonals. The molecular formula of the compound will be ................

$A$ solid $AB$ has a $ZnS$ type structure. If the radius of the $B^-$ ion is $100 \, pm$, what is the minimum radius of the $A^+$ cation in $pm$?

The space lattice of $CaF_2$ is:

For a tetrahedral structure,the limiting radius ratio $r_c^+ / r_a^-$ is .......

In a compound $AB$, $A$ atoms occupy the corners of the cube and the $B$ atoms occupy the body centre of the cube. If the $A$ atoms possess magnetic moment due to up-spin and $B$ atoms possess magnetic moment due to down-spin, the magnetic nature of the compound $AB$ in an isolated unit cell is
