The Structure of Metals Purdue University

The Structure of Metals and Other Monatomic Solids . The structures of pure metals are easy to describe because the atoms that form these metals can be thought of as identical perfect spheres. The same can be said about the structure of the rare gases (He, Ne, Ar, and so on) at very low temperatures.

Crystal structure

In crystallography, crystal structure is a description of the ordered arrangement of atoms, ions or molecules in a crystalline material. Ordered structures occur from the intrinsic nature of the constituent particles to form symmetric patterns that repeat along the principal directions of three dimensional space in matter.

Crystallography. The structure of crystals CSIC

A crystal is a material whose constituents, such as atoms, molecules or ions, are arranged in a highly ordered microscopic structure. These constituents are held together by interatomic forces (chemical bonds) such as metallic bonds, ionic bonds, covalent bonds, van der Waals bonds, and others. The crystalline state of matter is the state with the highest order, ie, with very high internal

Gold Nanoparticle Internal Structure and Symmetry

Shape and size are known to determine a nanoparticles properties. Hardly ever studied in synthesis, the internal crystal structure (i.e., particle defects, crystallinity, and symmetry) is just as critical as shape and size since it directly impacts catalytic efficiency, plasmon resonance, and orients anisotropic growth of metallic nanoparticles.
