1.	The ratio of closed packed atoms to tetrahedral holes in cubic close packing is `:`A. `1:1`B. `1:2`C. `1:3`D. `2:1`
Answer» Correct Answer - B Every constituent has two tetrahedral voids in ccp lattice atoms `=8xx(1)/(8)+6xx(1)/(2)=4` `therefore` Tetrahedral void `=4xx2=8`, thus ratio `=4:8::1:2`.
