Which of the following metals crystallizes in a cubic closest packing $(CCP)$ structure?

What is the type of hole occupied if the limiting value of $\frac{r+}{r-}$ is in the range of $0.225$ to $0.414$?

In a face-centred cubic $(FCC)$ unit cell,what is the total volume occupied by the atoms?

In a compound formed by atoms $A$ and $B$, atoms $A$ form a cubic close-packed $(CCP)$ structure, while atoms $B$ are located at the center of each edge. If the edge length of the cubic unit cell is $115 \ pm$, the distance of atom $A$ from the center of the cube is .......... $pm$.

What is the number of octahedral voids present in $0.2 \ mol$ of a compound forming $hcp$ structure?

Calculate the total number of tetrahedral and octahedral voids formed in $0.6 \ mol$ of a compound if it forms $hcp$ structure.
