Vedclass · Answer

(B) In crystal chemistry,an open structure refers to a crystal lattice arrangement where the atoms occupy a relatively small fraction of the total available volume. This typically occurs in structures with low packing efficiency,such as the simple cubic $(sc)$ lattice,where the packing fraction is only about $52.4\%$. In such structures,there is a significant amount of empty space (voids) between the constituent particles.
