Voids in close packed structures HD

Useful for CBSE, ICSE, NCERT & International Students Grade 12 Subject: Chemistry Lesson : The Solid State Topic: Voids in close-packed structures Any crystal lattice is made up of a very large number of unit cells and every lattice point is occupied by one constituent particle (atom, molecule or ion). There may be more than one type of void polyhedra in a single unit cell. These void polyhedra when put together fill space; however, in some cases only a part of a given polyhedron may lie within a unit cell. The size and distribution of voids in materials plays a role in determining In the close packed crystals (FCC, HCP) there are two types of voids - tetrahedral and octahedral voids (identical in both the structures as the voids are formed between two layers of atoms)..
