what are chemical and physical properties of iron?
31551
Iron is a lustrous, ductile, malleable, silver-gray metal (group VIII of the periodic table). It is known to exist in four distinct crystalline forms. Iron rusts in damp air, but not in dry air. It dissolves readily in dilute acids.

All matter has physical and chemical properties. ... Chemical properties describe the characteristic ability of a substance to react to form new substances; they include its flammability and susceptibility to corrosion. All samples of a pure substance have the same chemical and physical properties.

Iron is an element, as it is only one type of atom (Fe), which can be found along with all other elements in the Periodic Table of Elements . Compounds and mixtures both contain 2 or more elements within them, either bonded chemically (compound) or physically (mixture).

All steel contains iron, but it also contains carbon. ... The primary difference between iron and steel is that the former is a metal, whereas the latter is an alloy. Iron is simply a metal element that occurs naturally on Earth. In comparison, steel is a man-made alloy that's made by mixing iron and carbon together.

Raw Materials. The ores used in making iron and steel are iron oxides, which are compounds of iron and oxygen. The major iron oxide ores are hematite, which is the most plentiful, limonite, also called brown ore, taconite, and magnetite, a black ore.

Rust is clearly a substance that is different from iron. Rusting is an example of a chemical change. A chemical property describes the ability of a substance to undergo a specific chemical change. A chemical property of iron is that it is capable of combining with oxygen to form iron oxide, the chemical name of rust.
