Which among the following crystal lattices occupies all of the cubic holes by cations?
Which among the following crystal lattices occupies all of the cubic holes by cations?
$\mathrm{SrCl}_{2}$
$\mathrm{CaF}_{2}$
$\mathrm{CsCl}$
$\mathrm{UO}_{2}$
Solution
$\mathrm{CsCl}$
Cations inhabited all of the cubic holes in $\mathrm{CsCl}$ crystal lattices. A single atom in the cube's centre belongs to this unit cell, and the unit cell has only one body centre. As a result, the compound's formula is $\mathrm{CsCl}$, which stands for body-centred cubic cell. Particles are present in the corners of the cube, as well as one particle in the centre of the body, in this sort of cell.
