[1] [2] Many elements and compounds become metallic under high pressures, for example, iodine gradually becomes a metal at a pressure of between 40 and 170 thousand times atmospheric pressure. Sodium becomes a nonmetal at pressure of just under two million times atmospheric pressure, and at even higher pressures it is expected to become a metal ...
Aluminium also forms complex metallic alloys, like β–Al–Mg, ξ'–Al–Pd–Mn, and T ... with carbon as a major alloying element. Elinvar (nickel, chromium ...
From left to right: three alloys (beryllium copper, Inconel, steel) and three pure metals (titanium, aluminum, magnesium)An alloy is a mixture of chemical elements of which in most cases at least one is a metallic element, although it is also sometimes used for mixtures of elements; herein only metallic alloys are described.

The alkaline earth metals are six chemical elements in group 2 of the periodic table. They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). [1] The elements have very similar properties: they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure. [2]
The noble elements Gold and Platinum also have a comparatively high electronegativity for a metallic elements, thus alowing them to exist as single-metallic anions. For example: Cs + Au -> CsAu (Caesium Auride, a yellow crystalline salt with the Au − ion).
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.
For example, metallic cadmium was only found at two locations including the Vilyuy River basin in Siberia. [15] Native molybdenum has been found in lunar regolith and in the Koryakskii volcano in Kamchatka Oblast of Russia. [16] Elsewhere in this region native indium, aluminium, tantalum, tellurium, and other metals have been reported.
