An example of a body-centered cubic $(BCC)$ crystal structure is:

In a face-centered cubic $(FCC)$ lattice,$A$ atoms are present at the corners and $B$ atoms are present at the face centers. If one $B$ atom is removed from one of the face centers,what will be the molecular formula of the compound?

What is the coordination number of a sphere in a simple cubic lattice?

The edge length of the unit cell of $NaCl$ crystal lattice is $552 \, pm$. If the ionic radius of the sodium ion is $95 \, pm$, what is the ionic radius of the chloride ion in $pm$?

In antifluorite structure,the nearest neighbour distance is $20\sqrt{3} \ pm$. Then,the edge length of the unit cell is ............... $pm$.

The coordination number of $Cs^+$ in the crystal of $CsCl$ is ......
