CsCl crystallizes in a unit cell that contains the Cs+ ion at the center of a cube that has a Cl- at each corner. Each unit cell contains __________ Cs+ ions and __________ Cl-, ions, respectively.
Why, in a primitive cubic cell, do anions sit on the lattice points while the cation fills the lattice hole in the center a. Because it is favorable for anions to be as close to one another as possibl
