A solid or liquid (molten), opaque material with a lustrous surface and good electrical and thermal conductivities. Solid metal is usually crystalline and ductile and can be permanently deformed by shear on crystal planes; permanent deformation at temperatures below about 35–40% of the absolute melting point is accompanied by an increase in strength from strain or work hardening. Metallic properties are related to the arrangements of positively charged ions bonded through a surrounding field (sea) of free electrons that draw the ions into a close-packed crystalline structure with planes appropriate for slip. Liquids are nearly close packed, noncrystalline, with a thermal energy great enough to activate random, free movements of atoms. See also: Liquid
