Facts about iron
Here are a few interesting facts about iron element.
- Iron is the 4th most abundant element (by weight) present in the earth’s crust.
- Iron is a very ancient element (discovered around 5000 years ago) and it has been used for a very long time.
- There is a large amount of iron oxides on the planet Mars, which makes it look reddish in color.
- Most of the iron is present in the outer core as well as inner core of the earth’s crust.
- Sun, stars as well as meteors also contain iron element.
- Iron is very essential for living organisms. Plants use iron in the production of chlorophyll, while in animals the iron is a component of hemoglobin.
- Most of the iron is used in manufacturing of steels.
- China, Australia and Brazil are the largest producers of iron in the world.
- Iron is the most used metal on the earth and it is abundant and cheap.
Properties of iron
Here is a list of some physical properties and chemical properties of iron.
