Metals are elements and alloys which make good electrical conductors. The intermolecular structure of a metal promotes the sharing and movement of electrons.
in heraldry, the colors yellow (or) and white (argent). The rules of heraldry forbid placing color on color, or metal on metal.
A solid composed almost entirely of atoms of metallic elements; it is generally opaque, shiny, smooth, and malleable, and can conduct electricity.

(4) a class of chemical elements generally characterized by ductility, malleability, luster, and conductivity of heat and electricity, including alkali, alkali earth, base, heavy and precious metals. See also metalloid.
elements that are solids (except mercury), have few electrons in the outermost shell, and lose electrons easily to form cations. Metals of concern in AMD include iron, aluminum, manganese, and sometimes lead, mercury, copper, and zinc.
In one sense, jewelry is the art and science of crafting metals. Regardless of whether gemstones are present or not, virtually all jewelry incorporates some form of metal. Even bead and pearl necklaces normally incorporate some form of metalwork in the clasp. While 70 pure metals exist, only about 20 are used in the craft of jewelry making. Under controlled conditions (such as heating) metals are malleable and can be shaped into various designs. At room temperature, metals are solid and opaque.
ancient Greek coins could be made of Bi, gold, silver, bronze and electrum. Coins were made of the metal(s) most readily available in the region where the coins were minted.
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.
see Alloy, Bronze, Cast Iron, Lead, Steel, Tin, Wrought Iron
any of several chemical elements that are usually shiny solids that conduct heat or electricity and can be formed into sheets etc.
a chemical element characterised by high brightness (reflectivity) and good thermal and electrical conductivity
a composition of tin, copper and antimony
a lattice of ions swimming in a sea of electrons, so when you impose a microwave (electric vector in rotary motion) the photon-electron interactivity coefficient (frequency dependent) the electron will be put into motion (ie, electric current)
an element that has a crystalline structure when it is solid form
a special type of element
a substance composed of a great number of atoms, all of the same element that are all aligned together and all evenly share each others electrons
In astronomy a metal is any element heavier than Helium. This includes elements such as Carbon and Oxygen. Stars with an abundance of metals are said to have high metallicity.
Of the seven basic tinctures, only two are METALS. These are Argent and Or. Argent is silver, or white, while Or is Gold, or yellow.
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.
substances which have a complex chemical composition, luster and hardness and which can conduct heat and electricity and are opaque, and possess certain mechanical properties
A solid mineral element, such as bronze, copper or iron, that is able to conduct heat and electricity, is pliable under heat or pressure. Platinum, gold, and silver are considered precious metals.
An element that tends to lose electrons, forming positive ions, and is a good electrical conductor.
Any of a class of elements, or mixture of metallic elements, generally characterised by physical and chemical properties, including high conductance of heat and electricity, ductility, malleability, and lustre. Metallic elements can be replaced by the hydrogen of an acid to form a salt, and can form a "base" with a hydroxyl (OH) radical. Most coins are made of metal.
an element as specified on the periodic table to be so. Metals conduct heat and electricity, are malleable and ductile, and have high tensile strength.
the electroposite elements and alloys based on these elements.
An element that ionises to give positive ions.
One of the five elements, the sector governed by metal is in the north/northwest sector of the space. Metal energy is activated by the colors silver, gold and white.
Any of a category of electropositive elements that usually have a shiny surface, are generally good conductors of heat and electricity, and can be melted or fused, hammered into thin sheets, or drawn into wires. Typical metals form salts with nonmetals, basic oxides with oxygen, and alloys with one another
An element that forms positive ions when its compounds are in solution and for which the oxides form hydroxides rather than acids with water. Most metals are crystalline solids with metallic luster, are conductors of electricity, and have rather high chemical activity. Some metals are quite toxic.
Metal and earth element, represented by the symbol .
Metallic substances such as iron, foil, nickel, aluminum, gold, brass, lead, copper, silver, etc.
An opaque lustrous elemental chemical substance that is a good conductor of heat and electricity and, when polished, a good reflector of light; most elemental metals are malleable, ductile, and are generally denser than the other elemental substances; metals are structurally distinguished from nonmetals by their atomic bonding and electron availability; the electron band structure of metals is characterized by a partially filled valence band; the "free electrons" lost from the outer shells of metallic atoms are available to carry an electric current; the defining property of a metal is that it is an element with a positive thermal coefficient of resistivity, meaning the electrical resistivity of a metal continuously increases as temperature increases.
Yellow gold, white gold and platinum are the precious metals commonly used to craft fine jewelry.
an element, such as iron or copper, that are good conductors of heat and electricity, and have a characteristic luster.
Colors in heraldry indicating tincture, gold and silver. ( Or and Argent, respectively).
an element which has a characteristic lustrous appearance, is a good conductor of electricity and generally enters chemical reactions as a positive ion or cation. (E.g. nickel, copper, cobalt, zinc, cadmium, lead, mercury)
strong, malleable, ductile, sonorous, high melting/boiling points. Good conductors of heat and electricity.
High luster, heat and electricity conducting. Easily molded class of chemical element, with a crystalline structure. Very durable, they include gold, copper, iron and steel, etc.
A solid mineral element that is able to conduct heat and electricity and is pliable under heat or pressure. Common metals include bronze, copper and iron. Metals used for making jewelry, such as platinum, gold, and silver are called " precious metals".
Certain chemical elements solidify in a way that free electrons (electron gas) are present in the material. For this reason, metals show high electrical and heat conductivity. Metals are normally weldable and form with oxygen durable surface coatings.
an element that usually has a shiny surface, is a good conductor of heat and electricity, and can be melted down, fused, or hammered. Metals include iron, gold, sodium, copper, magnesium, tin, and aluminum.
An opaque, lustrous, elemental substance that is a good conductor of heat and electricity and, when polished, a good reflector or light. Most metals are malleable and ductile and are, in general, denser than other substances.
Also see Chien or Tui. One of five elements used as a remedy or corrective. It represents West and NW on the compass and bagua. Colors symbolized by white, silver, gold, copper, and metal colors. This element implies leadership.
an element that gives up electrons relatively easily and is typically lustrous, malleable, and a good conductor of heat and electricity.
In chemistry, a metal (Greek: Metallon) is an element that readily forms positive ions (cations) and has metallic bonds. Metals are sometimes described as a lattice of positive ions surrounded by a cloud of delocalized electrons. The metals are one of the three groups of elements as distinguished by their ionization and bonding properties, along with the metalloids and nonmetals.
Metal is one of the five elements of Chinese alchemy. The archetypal metal is silver. Metal is associated with the west and autumn, the planet Venus and the colour white.
