The ratio of cationic radius to anionic radius in an ionic crystal is greater than $0.732$. Its coordination number is

In a simple cubic unit cell,how many unit cells share each lattice point located at the corner?

In a face-centred cubic $(FCC)$ lattice,atoms of $A$ form the corner points and atoms of $B$ form the face-centred points. If two atoms of $A$ are missing from the corner points,the formula of the ionic compound is

What is the coordination number of $Cs^{+}$ and $Cl^{-}$ ions in the $CsCl$ structure?

An ionic compound has unit cells consisting of $A$ ions at the corners of a cube and $B$ ions on the centres of the faces of the cube. The empirical formula of this compound is

What is the coordination number of $Cu$ in a face-centered cubic $(fcc)$ lattice?
