Which of the following metals has a $ccp$ crystal structure?

In the face-centred cubic $(FCC)$ lattice structure of gold, the closest distance between gold atoms is ('a' being the edge length of the cubic unit cell).

Find the radius of an atom in $fcc$ unit cell having edge length $393 \ pm$. (in $pm$)

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

An element has a $bcc$ structure with $12.08 \times 10^{23}$ unit cells. What is the total number of atoms in these unit cells?

In $CsCl$ lattice,the coordination number of $Cs^{+}$ ion is:
