What is the co-ordination number of an atom in each of the following types of cubic lattices ? (a) Primitive (b) Body centred. |
|
Answer» Solution :(a) In Primitive cubic lattice, each ATOM is in direct CONTACT with six other atoms. So the co-ordination number of primitive cubic lattice is 6. (B) In body CENTRED cubic lattice, each atom is in direct contact with EIGHT other atoms, So the co-ordination number of body centred cubic lattice is 8. |
