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

Which type of cubic lattice has the maximum number of atoms per unit cell?

$A$ cubic structure is formed where atoms of element $X$ are occupied at the corners of the cube and also at the face centers. Atoms of element $Y$ are present at the body center and at the edge centers. If all the atoms are removed along a plane passing through the middle of the cube (bisecting the four edges), the formula will become

The interionic distance for $Cesium$ $chloride$ $(CsCl)$ crystal will be (where $a$ is the edge length of the unit cell):

Number of next nearest ions around $Na^{+}$ in $NaCl$ unit cell is $X$ and number of next nearest ions around $Cs^{+}$ in $CsCl$ unit cell is $Y$. The value of $X - Y$ is

What is the total volume occupied by atoms in a face-centered cubic $(FCC)$ unit cell of a metal?
