Question

Answer

Iron is a chemical element with the symbol Fe and atomic number 26. It is a metal in the first transition series and is the most common element on Earth by mass. Iron is a key component in the production of steel, which is used in a wide range of applications such as construction, transportation, and manufacturing. Iron is also an essential nutrient for many living organisms, including humans, and plays a vital role in the production of hemoglobin, a protein found in red blood cells that carries oxygen throughout the body. Iron can be found in a variety of forms, including pure iron, iron oxide, and iron sulfide, and is commonly extracted from iron ore through a process called smelting.

Answer

Iron is a chemical element with the symbol Fe 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. It is a crucial element in the formation of steel, which is used to make tools, machinery, and many other products. Iron is also important for the human body, as it is a component of hemoglobin, the protein that carries oxygen in the blood. Iron is found in many foods, including red meat, poultry, fish, beans, and fortified cereals. However, excessive intake of iron can be harmful and lead to iron toxicity.
