Question

The ABC ABC type packing is called cubic close packing (ccp).
If true enter 1,else enter 0.

Answer 1

In the diagram on the above, the blue atoms have been placed above the white (unoccupied) void spaces in layer A. Since this third layer is displaced horizontally (in our view) from layer A, we will call it layer C. As we add more layers of atoms, the sequence of layers is A-B-C-A-B-C-A-B-C...So, we call it ABC packing or cubic close packing.
