For an ionic crystal of the type $AB$,the value of the limiting radius ratio is $0.40$. This value suggests that the crystal structure should be:

$A$ solid has a structure in which $W$ atoms are located at the corners of a cubic lattice,$O$ atoms are at the center of the edges,and $Na$ atoms are at the center of the cube. The formula for the compound is:

If the edge length of a cubic unit cell in an $fcc$ structure is $620 \ pm$, then the atomic radius of the element will be ............... $pm$.

The number of hexagonal faces that are present in a truncated octahedron is

What is the coordination number of $Cu$ in a face-centered cubic $(fcc)$ lattice?

The structure of $MgO$ is similar to $NaCl$. What would be the coordination number of magnesium?
