1.	The Ca^(2+) and F^(-)ions are located in CaF_(2) crystal, respectively at face centred cubic lattice points and in
Answer» TETRAHEDRAL void half of tetrahedral points octahedral points half of octahedral VOIDS. Solution :In `CF^(2)` crystal, `Ca^(2^+)`ions are present at all CORNERS and atthe centre of each face of thecube and `F^(-)` ions occupy all the tetrahedral voids.
