In Beryllium-crystal the layers of atoms are being stacked In a pattern of ABABAB- type of arrangement.Calculate the number of tetrahedral and,octahedral voids present in 0.5 mol of Be crystal

Explain tetrahedral void in close packing.

Statement 1: In crystal lattice, the size of the tetrahedral void is larger than an octahedral void. Statement 2: The cations occupy less space than anions in crystal packing.

The number of tetrahedral voids in the unit cell of a face centred cubic lattice of similar atoms is

Assertion : A tetrahedral void is surrounded by four spheres and an octahedral void is surrounded by six spheres. Reason : In hcp or ccp the number of tetrahedral voids is double the number of close packed spheres and number of octahedral voids is equal to number of close packed spheres.

In a crystal system, anions B are in ccp arrangement . Cations A occupy 50% of octahedral voids and 50% tetrahedral voids. Its formula of representation is
