In chemistry, metals are materials whose atoms are united by
metallic bonds. They are simple bodies or alloys which are generally
hard, opaque, shiny, good conductors of heat and electricity. They are
generally malleable, i.e. they can be hammered or pressed to make them
change shape without cracking or breaking them. Many substances which
are not classified as metallic at atmospheric pressure can acquire
metallic properties when subjected to high pressures. Metals have many
common applications, and their consumption has increased significantly
since the 1980s, to the point that some of them have become critical
mineral raw materials.
In astrophysics, and in particular in stellar physics, any chemical element other than hydrogen and helium is called metal. These elements are produced by stellar nucleosynthesis from hydrogen and helium by nuclear fusion, the process at the origin of the energy released by the stars. From this point of view, the metallicity of a star is the proportion of elements other than hydrogen and helium which constitute it.
The electrons of pure or alloyed metallic materials are distributed in energy levels forming a continuum between the valence band, occupied by the valence electrons, and the conduction band, occupied by the free electrons thermally injected from the valence band beyond the Fermi level. These free electrons form a delocalized metallic bond throughout the volume of the material. We can imagine a metal as a three-dimensional network of metal cations bathed in a fluid of very mobile electrons. The free electron model calculates the electrical conductivity and the contribution of electrons to the heat capacity and thermal conductivity of metals, although this model does not take into account the structure of the crystal lattice of the metal. Some materials, such as intermetallic, have partially metallic bonds and are therefore at the limit of ceramics.
The particular electronic nature of a metal bond is responsible for several macroscopic properties of metals: the free electron fluid ensures both high electrical conductivity and thermal conductivity by allowing the circulation of an electric current and promoting propagation phonons in the material; it accounts for the ductility, malleability and plasticity of metals while maintaining their cohesion in the event of deformation breaking the other interatomic bonds; it gives metals their particular absorbance and luster by its interaction with electromagnetic waves, as well as their higher melting point and boiling point than non-metals by strengthening the other types of interatomic bonds. The latter, in particular the covalent coordination bonds, are responsible for the different crystal structures formed by solid metals: the most frequent is the centered cubic structure, followed by the compact hexagonal structure and the centered faces cubic structure.
In a centered cubic structure, each atom is located in the center of a cube formed by its eight neighboring atoms. In cubic structures with centered faces and compact hexagonal, each atom is surrounded by twelve other atoms, but the stacking of these atoms differs between these two structures. Some metals can adopt different crystal structures depending on the temperature and pressure to which they are subjected.
