{i} any of several solid mineral elements (such as gold, silver, copper, etc.) that are malleable under heat or pressure and can conduct heat and electricity; element yielding positively charged ions in watery solutions of its salts
Any of a number of chemical elements in the periodic table that form a metallic bond with other metal atoms; generally shiny, somewhat malleable and hard, often a conductor of heat and electricity
No sharp line can be drawn between the metals and nonmetals, and certain elements partake of both acid and basic qualities, as chromium, manganese, bismuth, etc
An elementary substance, as sodium, calcium, or copper, whose oxide or hydroxide has basic rather than acid properties, as contrasted with the nonmetals, or metalloids
Metal is a hard substance such as iron, steel, gold, or lead. pieces of furniture in wood, metal and glass He hit his head against a metal bar. see also base metal. a hard, usually shiny substance such as iron, gold, or steel metallic (metallum , from metallon). Any of a class of substances with, to some degree, the following properties: good heat and electricity conduction, malleability, ductility, high light reflectivity, and capacity to form positive ions in solution and hydroxides rather than acids when their oxides meet water. About three-quarters of the elements are metals; these are usually fairly hard and strong crystalline (see crystal) solids with high chemical reactivity that readily form alloys with each other. Metallic properties increase from lighter to heavier elements in each vertical group of the periodic table and from right to left in each row. The most abundant metals are aluminum, iron, calcium, sodium, potassium, and magnesium. The vast majority are found as ores rather than free. The cohesiveness of metals in a crystalline structure is attributed to metallic bonding: The atoms are packed close together, with their very mobile outermost electrons all shared throughout the structure. Metals fall into the following classifications (not mutually exclusive and most not rigidly defined): alkali metals, alkaline earth metals, transition elements, noble (precious) metals, platinum metals, lanthanide (rare earth) metals, actinide metals, light metals, and heavy metals. Many have essential roles in nutrition or other biochemical functions, often in trace amounts, and many are toxic as both elements and compounds (see mercury poisoning, lead poisoning). alkali metal alkaline earth metal heavy metal metal fatigue metal point rare earth metal scrap metal
A mineral source that is a good conductor of electricity and heat, and yield basic oxides and hydroxides One of the hidden treasures in garbage
a substance or mixture that has a characteristic luster, or shine, is generally a good conductor of heat and electricity, and is malleable and ductile
A mass of material that is composed of a single element that is characterized by specific characteristics of opacity, ductility, conductivity, and luster Some common metals are copper, silver, and gold
a substance that is malleable and ductile, has a characteristic luster, and is generally a good conductor of heat and electricity The bands of a metal are partially filled
Refers to aircraft (thus metal) of the airline you are flying (i e , Delta metal, American metal, etc )
An element below and to the left of the stepwise division (metalloids) in the upper right corner of the periodic table; about 80% of the known elements are metals
