atomic packing

Atomic packing refers to how atoms are arranged in a material, such as a metal or mineral, affecting its density and strength. Think of atoms like building blocks that occupy space; how tightly these blocks fit together determines the material's packing efficiency. There are different patterns—like simple layers or more complex arrangements—that influence properties like appearance and durability. A higher packing efficiency means fewer gaps between atoms, often resulting in a stronger, denser material. Understanding atomic packing helps scientists predict and tailor the properties of materials for various applications.
