These are general aspects of iron, and its significance varies across scientific, industrial, and nutritional contexts.

Description
Product Details

Chemical Symbol: Fe is the chemical symbol for iron on the periodic table.
Elemental Properties: Iron is a metallic chemical element with atomic number 26. It is a transition metal, and it is one of the most abundant elements on Earth.
Physical Properties: Iron is known for its strength, malleability, and magnetic properties. It has a silver-gray appearance.
Biological Significance: Iron is an essential element for living organisms. It plays a crucial role in various biological processes, including oxygen transport in the blood (as part of hemoglobin), energy metabolism, and DNA synthesis.
Dietary Iron: Iron is an important dietary mineral. It can be found in both animal and plant-based foods. Heme iron, found in animal sources, is more easily absorbed by the body than non-heme iron found in plant sources.
Iron Deficiency: Iron deficiency can lead to anemia, a condition characterized by a reduced ability of the blood to carry oxygen. Iron supplements or dietary changes are often recommended to address iron deficiency.
Industrial Uses: Iron and its alloys, such as steel, have numerous industrial applications. Steel, which is primarily composed of iron and carbon, is widely used in construction, transportation, and manufacturing.
Magnetic Properties: Iron is known for its magnetic properties. It can be magnetized and is used in the production of magnets.
Ores: Iron is commonly extracted from iron ores, mainly hematite (Fe2O3) and magnetite (Fe3O4), through processes like smelting.
Corrosion: Iron is susceptible to corrosion, forming rust (iron oxide) when exposed to oxygen and moisture. Protective coatings, such as paint or galvanization, are often applied to prevent rusting.
