Chemistry - Solid State Question with Solution | TestHub

A crystal system is hexagonal if its unit cell having$\mathrm{a}=\mathrm{b}\ne \mathrm{c}$axial ratio and
$\mathrm{\alpha }=\mathrm{\beta }=90°,$$\mathrm{\gamma }=120°$axial angles. Crystal of$\mathrm{A}\mathrm{g}\mathrm{B}\mathrm{r}$has both Schottky defect and Frenkel defect. Frenkel defect is shown by ionic solid having low coordination number.
