1.	KF has ccp structure . Calculate the radius of unit cell if the side of the cube or edge length is 400 pm . How many F ions and octahedral voids are there in this unit cell ?
Answer» SOLUTION :For ccp lattice `r=(sqrt2a)/(4) or r=(1.414xx"400 pm")/(4) or r=141.4" pm"` There are `4F^(-)` IONS and 4 octahedral VOIDS.
