Vedclass · Answer

(C) In crystal structures,close-packed structures are those where atoms are packed as efficiently as possible to minimize empty space. $hcp$ (hexagonal close-packed),$ccp$ (cubic close-packed),and $fcc$ (face-centered cubic) are all examples of close-packed structures with a packing efficiency of $74\%$. $bcc$ (body-centered cubic) has a packing efficiency of $68\%$,which is lower than the close-packed structures. Therefore,$bcc$ is not considered a close-packed structure.
