How will you distinguish between the following pair of terms :
(i) hexagonal close-packing and cubic close-packing?
(ii) crystal lattice and unit cell ?
(iii) tetrahedral void and octahedral void?
in a crystalline solid, anions B are arranged in a cubic close packing. cations are equally distributed between octahedral and tetrahedral voids. if all the octahedral voids are occupied, what is the formula of the solid
