In the zinc blende structure,zinc atoms fill up:

$A$ compound is formed by elements $A$ and $B$. This crystallises in the cubic structure where the $A$ atoms are at the corners of the cube and $B$ atoms are at the body centres. The simplest formula of the compound is

How many chloride ions are there around a sodium ion in a sodium chloride crystal?

The number of atoms contained in one face-centred cubic $(FCC)$ unit cell of a monoatomic substance is:

The ionic radii of $A^{+}$ and $B^{-}$ ions are $0.98 \times 10^{-10} \ m$ and $1.81 \times 10^{-10} \ m$. The coordination number of each ion in $AB$ is.......

Body centered cubic lattice has a coordination number of
