In the structure of a solid,$W$ atoms are located at the cube corners of the unit cell,$O$ atoms are located at the cube edges,and $Na$ atoms are at the cube centers. The formula of the compound is:

In an ionic crystal,ion $A$ is present at the corners of the cubic unit cell,and ion $B$ is present at the centers of the faces. What is the formula of this ionic compound?

The number of octahedral voids per lattice site in a lattice is $...$ (Rounded off to the nearest integer).

What is the coordination number of each atom in $hcp$ or $ccp$ structure?

$A$ and $B$ atoms in a crystal are positioned at the corners and face centers respectively. What is the formula of the crystal?

In an alloy of metals $M$ and $N$,$N$ atoms form a $bcc$ structure,while $M$ atoms occupy the center of each face. If the cube is cut such that all atoms along one body diagonal are removed,the formula of the resulting solid will be ...........
