Homework Statement
Chapter name: Solid state
Topic: close packed structures in crystalline solids
Sub-topic: close packing in 3D
In my Chemistry book I read:
Let the number of closed packed spheres be N, then:
The number of octahedral voids generated=N
The number of tetrahedral voids generated=2N
Now let us suppose there is 1 sphere only. Can anybody explain to me where the one octahedral void and two tetrahedral voids are? I cannot understand how they deduced the above formula. There is no explanation given in the book. It just says: "It is found that such and such thing happens". No illustration is provided. I thought that I could find the answer to my problem on this forum.
Homework Equations
If N is the number of spheres, then
number of octahedral voids=N
number of tetrahedral voids=2N
The Attempt at a Solution
No clue. If possible, please answer with pictures/graphics.
Thanks
Eagerly waiting!
Mr V
