What is the total number of ions present in one unit cell of sodium chloride lattice?

In the rock salt structure,the $ccp$ arrangement of $Cl^{-}$ ions creates tetrahedral voids,which are....

Explain the calculation of the number of atoms in a primitive cubic unit cell.

In the face-centred cubic $(FCC)$ lattice structure of gold, the closest distance between gold atoms is ('a' being the edge length of the cubic unit cell).

If the length of the body diagonal of a cube is $x$,then the tetrahedral void will be at a distance of ....... from the center of the cube.

In solid $CsCl$,each $Cl^{-}$ ion is closely packed with how many $Cs^{+}$ ions?
