This article provides basic information on the chemical elements and their arrangement into a periodic table based on recurring similarities in the fundamental nature of the elements. These elements follow a periodic pattern related to the electron configuration that allows them to be arranged into the convenient periodic table.

The crystal structure of a material is an important aspect of corrosion and oxidation processes. This article provides a general introduction to the crystal structure of materials, providing information on the crystal systems, lattice dimensions, nomenclature, and solid-solution mechanisms used to characterize structures. It illustrates the unit cells and...
