- For other uses, see Iron (disambiguation). Iron is a chemical element with symbol Fe (from Latin: ferrum) and atomic number 26. It is a metal in the first transition series. It is by mass the most common element on Earth, forming much of Earth's outer and inner core. It is the fourth most common element in the Earth's crust.

- Metals are atoms that attach themselves to other atoms in a particular way. Metal atoms, because of how their electrons are arranged, lose their electrons easily. When they join up with other atoms to make molecules, metal atoms join together by exchanging electrons.Because metal atoms join other metal atoms in this special way, most metal is shiny, soft, and easy to bend.Most metals are also good conductors of electricity-that is, electrons move easily from one atom of metal to the next. (That's why we make electric wires out of copper).ecause metal atoms join other metal atoms in this special way, most metal is shiny, soft, and easy to bend.

- In chemistry, the term base metal is used informally to refer to a metal that oxidizes or corrodes relatively easily, and reacts variably with dilute hydrochloric acid (HCl) to form hydrogen. Examples include iron, nickel, lead and zinc.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.

- Ores are naturally occurring rocks that contain metal or metal compounds in sufficient amounts to make it worthwhile extracting them. For example, iron ore is used to make iron and steel. metal ore is a rock containing a metal, or a metal compound, in a high enough concentration to make it economic to extract the metal. The method used to extract metals from the ore in which they are found depends on their reactivity.

Top 10 Most Expensive Metals in the World Increase your knowledge with top 10 most expensive metals in the world. A metal is an element, compound, or alloy that is a good conductor of both electricityand heat. Metals are usually malleable and shiny, that is they reflect most of incident light. In a metal, atoms readily lose electrons to form positiveions (cations).

- Metal crystals refers to the metallic crystal structure of metals. When metals freeze and form a solid, the atoms actually form crystals. And this metallic crystal structure o…f different metals and alloys has a profound effect on the strength and other physical properties of those materials.   Though mercury, copper, iron and tungsten are said to form metallic crystals, the idea can be expanded a bit to include metals in general.

Teacher and Technician sheet Mixture; Metal; Element; Crystal. In its scientific usage, the term metal means a metallic element. An alloy is a mixture or solid solution composed of a metal and another element. But in everyday language, we often use the word metal to describe what an alloy is. That is because a mixture of metallic elements is called an alloy. Iron is a metal element. Steel is a mixture of iron with other elements such as carbon, nickel, chromium, etc. and so is an alloy. An alloy is a mixture of either pure or relatively pure chemical elements, forming an impure substance retaining the characteristics of a metal. Alloy constituents are usually measured by mass.

A certain element is a gas at room temp. Therefore, it is most likely a metal, metalloid, nonmetal, or halogen? In chemistry, a metal 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. On the periodic table, a diagonal line drawn from boron (B) to polonium (Po) separates the metals from the nonmetals.

- A metal is a lattice of positive metal 'ions' in a 'sea' of delocalised electrons. Metallic bonding refers to the interaction between the delocalised electrons and the metal nuclei. The physical properties of metals are the result of the delocalisation of the electrons involved in metallic bonding.

metal metal. 1  any of a class of chemical elements, as iron, gold, or aluminum, generally characterized by ductility, malleability, luster, and conductivity of heat and electricity: these elements act as cations in chemical reactions, form bases with the hydroxyl radical, and can replace the hydrogen of an acid to form a salt.
