Comparison OF HCP and CCP || Location OF Tetrahedral void and Coordination Number in Close Packing || CCP || HCP || Some very important Results

The coordination number in hcp is

HCP unit cell number of atoms

Assertion (A) : hcp is more closely packed than ccp . Reason (R ) : hcp has a CN of 12 , whereas ccp has a CN of 8 .

If the total number of atoms per unit cell in an hcp structure and a bcc structure gets halved, then ratio of percentage voids in hcp and bcc structures is

The fcc structure is often called
