Metal, any of a class of substances characterized by high electrical and thermal conductivity as well as by malleability, ductility, and high reflectivity of light. Approximately three-quarters of all known chemical elements are metals. Learn more about metals in this article.
The highlighted elements are considered the metal elements. Most elements on the periodic table are metals. They are grouped together in the middle to the left-hand side of the periodic table. The metals consist of the alkali metals, alkaline earths, transition metals, lanthanides, and actinides.
The meaning of METAL is any of various opaque, fusible, ductile, and typically lustrous substances that are good conductors of electricity and heat, form cations by loss of electrons, and yield basic oxides and hydroxides; especially : one that is a chemical element as distinguished from an alloy.
