Vedclass · Answer

(C) In structure $I$,the central void is surrounded by $6$ atoms (at the center of the unit cell),which represents an octahedral void.In structure $II$,the void is at the edge center,surrounded by $6$ atoms,which also represents an octahedral void.In structure $III$,the void is surrounded by $4$ atoms in a tetrahedral arrangement,which represents a tetrahedral void.Therefore,$I$ and $II$ represent octahedral holes.

Identify the types of voids represented by the structures $I$,$II$,and $III$ in the given image.
