In a body-centered cubic $(BCC)$ unit cell,how many metal atoms surround the metal atom located at the center of the cell?

In a solid $AB$ having the $NaCl$ structure,$A$ atoms occupy the corners of the cubic unit cell. If all the face-centered atoms along one of the axes are removed,then the resultant stoichiometry of the solid is

What are the number of atoms per unit cell in $BCC$ and $FCC$ respectively?

$A$ solid $A^{+}B^{-}$ has a $NaCl$ type close-packed structure. If the radius of the anion is $250 \ pm$, what should be the ideal radius of the cation in $pm$?

The number of atoms/molecules contained in one body-centered cubic unit cell is

The intermetallic compound $LiAg$ crystallizes in a cubic lattice in which both lithium and silver have a coordination number of $8$. The crystal class is
