If the radius ratio is in the range of $0.414 - 0.732,$ then the coordination number will be

For an ionic crystal $A^{+}B^{-}$ with coordination number $6$,the radius ratio will be

$A$ compound $M_pX_q$ has a cubic close packing $(ccp)$ arrangement of $X$. Its unit cell structure is shown below. The empirical formula of the compound is

The unit cell of a binary compound of $A$ and $B$ metals has a $ccp$ structure with $A$ atoms occupying the corners and $B$ atoms occupying the centres of each face of the cubic unit cell. If during the crystallisation of this alloy,two $A$ atoms are missing from the unit cell,the overall composition per unit cell is:

In a body-centered cubic $(BCC)$ unit cell,how many metal atoms surround the metal atom located at the center of the cell?

What is the coordination number of each atom in a $bcc$ structure?
