The metallic mean (also metallic ratio, metallic constant, or noble mean [1]) of a natural number n is a positive real number, denoted here , that satisfies the following equivalent characterizations: the unique positive real number such that = +
A metallic glass (also known as an amorphous or glassy metal) is a solid metallic material, usually an alloy, with a disordered atomic-scale structure. Most pure and alloyed metals, in their solid state, have atoms arranged in a highly ordered crystalline structure.
This word-use is distinct from the conventional chemical or physical definition of a metal as an electrically conducting solid. Stars and nebulae with relatively high abundances of heavier elements are called "metal-rich" when discussing metallicity, even though many of those elements are called nonmetals in chemistry.
The metallic radius is defined as one-half of the distance between the two adjacent metal ions in the metallic structure. This radius depends on the nature of the atom as well as its environment—specifically, on the coordination number (CN), which in turn depends on the temperature and applied pressure.
An amorphous metal (also known as metallic glass, glassy metal, or shiny metal) is a solid metallic material, usually an alloy, with disordered atomic-scale structure. Most metals are crystalline in their solid state, which means they have a highly ordered arrangement of atoms .
The chemical elements can be broadly divided into metals, metalloids, and nonmetals according to their shared physical and chemical properties.All elemental metals have a shiny appearance (at least when freshly polished); are good conductors of heat and electricity; form alloys with other metallic elements; and have at least one basic oxide.
Metallic bonding, type of chemical bonding; Metallicity, in astronomy the proportion of elements other than helium and hydrogen in an object; Metallic color, a color that gives the appearance of metal; Metallic dragon, a classification of dragon found in the role playing game Dungeons & Dragons; Metallic paint, paint that provides the ...
Metallic paint, which may also be called metal flake (or incorrectly named polychromatic), is a type of paint that is most common on new automobiles, but is also used for other purposes. Metallic paint can reveal the contours of bodywork more than non-metallic, or "solid" paint.
