If atom A forms the close packing B occupies 1/4 the octahedral void and C occupies the 1/4 the tetrahedral void, find the formula of the compound.

answered-by-expert Expert Answer

Step 1--- If n number of A forms the close packing 2n tetrahedral voids will be formed and n octahedral void will be formed.

Step 2---- If 1/4 the Tetrahedral voids and 1/4 the octahedral voids are occupied then the ratio will be nA : n x 1/4 B : 2n x 1/4 C = A : 1/4 B : 1/2 C, formulas are whole number so multiply by 4

Step 3--- The formula of the compound is A4BC2

sir in types of unit cell we studied it can be of 4 types i.e primitive, face centred, body centred and end centred, but while studing 3D close packing it was told that it can be of 3 types i,e. simple(primitive) cubic unit cell, hcp and ccp. but i am not able  to understand that hcp is a type of unit cell or it is one of the 7 crystal system or somthing else?and if it is type of unit cell then why it is not taught under the topic types of unit cell. and if it is a crystal system then what about the rest 6 crystal system, then why rest 6 crystal system does not comes under 3 dimensional close packing?
