what is definition of closed packing?a close packing plane is a plane that the atoms cannot be packed any closer?
The discussion centers on the concept of "close packing," which refers to the arrangement of spheres in three-dimensional space such that they cannot be packed any closer together. Two primary configurations are identified: cubic close packing and hexagonal close packing, both of which relate to the density of spheres. The conversation also clarifies that while the term is often applied in 3D, close packing can also be relevant in two-dimensional arrangements. Key resources provided include links to animations and detailed explanations of these packing concepts.
PREREQUISITESChemists, materials scientists, and students studying crystallography or solid-state physics will benefit from this discussion on close packing and its implications in atomic arrangements.
That's "close packing,", not "closed." Yes, it means that atoms, taken as spheres, cannot be closer to one-another.

atoms have to be sphere? in definition word sphere is present?DrClaude said:it means that atoms, taken as spheres, cannot be closer to one-another.
what about 2D?is close packing not applied in 2D?DrClaude said:, i.e., how to arrange spheres in 3D
Yes, you can apply it to 2D. It is just that crystal lattices are usually 3D. I'm sorry if I led you astray by discussing spheres in 3D. But the links I gave also discuss the 2D case.gracy said:what about 2D?is close packing not applied in 2D?
Thanks a lot.May God bless you.DrClaude said:Yes, you can apply it to 2D. It is just that crystal lattices are usually 3D. I'm sorry if I led you astray by discussing spheres in 3D. But the links I gave also discuss the 2D case.
