A compound of formula $\displaystyle \mathrm{A}_2 \mathrm{~B}_3$ has the hcp lattice. Which atom forms the hcp lattice and what fraction of tetrahedral voids is occupied by the other atoms :
Official answer
(4)
$\displaystyle \begin{aligned}
& \text { hcp lattice - B, } \frac{1}{3} \text { Tetrahedral } \\
& \text { voids - A }
\end{aligned}$
