rautaatomi

Rauta-atomi refers to an atom of the chemical element iron. Iron, with the chemical symbol Fe and atomic number 26, is a fundamental element essential to many natural processes and human endeavors. In its atomic form, iron consists of a nucleus containing 26 protons and typically 26 to 30 neutrons, surrounded by 26 electrons. The arrangement of these electrons dictates iron's chemical behavior and its tendency to form various compounds.

Iron is a transition metal, characterized by its metallic luster, high density, and malleability. It is a good conductor of heat and electricity. Naturally occurring iron is found in several isotopes, with iron-56 being the most abundant. The electronic configuration of a neutral iron atom is [Ar] 3d6 4s2, which allows it to readily lose electrons and form positive ions, most commonly Fe2+ and Fe3+. These ions are crucial for biological functions, such as oxygen transport in hemoglobin.

Industrially, iron is one of the most important metals, forming the basis of steel, a vital alloy used in construction, manufacturing, and transportation. Understanding the rautaatomi is key to comprehending the properties and applications of iron and its countless compounds.
