Determine the number of atoms per unit cell in a body-centered cubic $(BCC)$ unit cell.

In a solid $AB$,$A$ atoms are in $ccp$ arrangement and $B$ atoms occupy all the octahedral sites. If two atoms from the opposite faces are removed,then the resultant stoichiometry of the compound is $A_{x} B_{y}$. The value of $x$ is ..... [nearest integer]

What is the coordination number of a cation present in a tetrahedral void?

The first three nearest neighbour distances for a body-centered cubic $(BCC)$ lattice are respectively:

If $a$ is the length of the side of a cube,the distance between the body-centered atom and one corner atom in the cube will be

In a diamond crystal,each carbon atom is linked with other carbon atoms. The number of carbon atoms in a diamond unit cell is:
