Question

Coordination number of BCC lattice

Answer 1

co-orfination number :- no of particles N contact with central particle , then we say that co-ordination of Central particle is N .

now , in BCC lattice central one particle contact with 8 another particle ,
4 above and 4 below . hence co-ordination number of BCC lattice is equal to 8 .

Answer 2

Hi friend,
CO-ORDINATION NUMBER:-
No of particles in contact with central particle , then we say that co-ordination of Central particle is in.

In bcc there is a one atom at centre and it is surrounded by 8 atoms which is in contact with 8 other unit cells.

Ex:- cesium chloride (cscl).
