Rautaatomien

Rautaatomien refers to iron atoms. Iron is a chemical element with the symbol Fe and atomic number 26. It is a metal that belongs to the first transition metal series. Pure iron is a soft, lustrous, silvery-white metal. It is highly reactive and readily oxidizes, forming rust. In its elemental form, iron is rarely found on Earth's surface because of its reactivity. It is most commonly found in meteorites and in the Earth's core.

Iron atoms have a nucleus containing 26 protons and typically 28 neutrons, although isotopes of iron exist with varying numbers of neutrons. The atomic mass of iron is approximately 55.845 atomic mass units. Each iron atom has 26 electrons, arranged in specific energy shells. The electron configuration of iron is [Ar] 3d6 4s2. This configuration is responsible for iron's chemical properties, including its ability to form multiple oxidation states, most commonly +2 and +3.

The significance of iron atoms extends to their role in biology and industry. Iron is an essential trace element for most living organisms, playing a crucial role in oxygen transport in the blood through hemoglobin and in cellular respiration. Industrially, iron is the most widely used metal, forming the basis of steel production, which is fundamental to construction, manufacturing, and infrastructure worldwide. The properties of iron atoms, such as their magnetic behavior and their tendency to form alloys, make them indispensable in modern technology.
