- Definition of Metals. Elements that form cations when compounds of it are in solution and oxides of the elements form hydroxides rather than acids in water.Most metals are conductors of electricity, have crystalline solids with a metallic luster and have a high chemical reactivity.he metal series includes all elements of the alkali, alkali-earth, inner-transition (lanthanides and actinides series), transactinides and transition series as well as some elements of the metalloid series (elements: Ge, Sb and Po).

Iron (Chem.) The most common and most useful metallic element, being of almost universal occurrence, usually in the form of an oxide (as hematite, magnetite, etc.), or a hydrous oxide (as limonite, turgite, etc.). It is reduced on an enormous scale in three principal forms; viz., cast iron, steel, and wrought iron.

Iron A chunk of iron. Iron (chemical symbol Fe) is a chemical element and a metal. It is the second most common metal on Earth, and the most widely-used metal. It makes up much of the Earth's core, and is the fourth most common element in the Earth's crust. Iron is element 26, a transition metal in Group 8.

Metalloid A metalloid is a chemical element with properties in between, or that are a mixture of, those of metals and nonmetals. There is no standard definition of a metalloid, nor is there complete agreement as to which elements are appropriately classified as such.Despite this lack of specificity, the term remains in use in the literature of chemistry.here is no standard definition of a metalloid, nor is there complete agreement as to which elements are appropriately classified as such.

- A pure metal is an element. Some metals are alloys, which mean they have more than one metal or element in them. The metal bronze is made … of two elements, the metal tin and the metal copper.

- About 91 of the 118 elements in the periodic table are metals (some elements appear in both metallic and non-metallic forms). Astrophysicists use the term metal to collectively describe all elements other than hydrogen and helium.hen a metal ore is an ionic compound of that metal and a non-metal, the ore must usually be smelted — heated with a reducing agent — to extract the pure metal. Many common metals, such as iron, are smelted using carbon as a reducing agent.

A certain element is a gas at room temp. Therefore, it is most likely a metal, metalloid, nonmetal, or halogen? Most elements on this line are metalloids, sometimes called semi-metals; elements to the lower left are metals; elements to the upper right are nonmetals. A modern definition of metals is that they have overlapping conduction bands and valence bands in their electronic structure. This definition opens up the category for metallic polymers and other organic metals, which have been made by researchers and employed in high-tech devices.
