What is the total number of adjacent unit cells shared by each face particle of an $fcc$ unit cell?

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

$A$ crystal is made up of metal ions $M_1$ and $M_2$ and oxide ions. Oxide ions form a $ccp$ lattice structure. The cation $M_1$ occupies $50 \%$ of octahedral voids and the cation $M_2$ occupies $12.5 \%$ of tetrahedral voids of the oxide lattice. The oxidation numbers of $M_1$ and $M_2$ are,respectively:

If the radius ratio is in the range of $0.732 - 1.000$,then the coordination number will be

How many total constituent particles are present in a simple cubic unit cell?

In a face centered cubic lattice,atoms $A$ are at the corner points and atoms $B$ are at the face centered points. If one atom $B$ is missing from one of the face centered points,the formula of the ionic compound is:
