Iron is a silvery, white metal that you can find in rocks. Its chemical symbol is Fe, for ferrum. It has 26 protons and a mass of 56.

The industry gets pure iron out of ore that is melted at a high temperature about 1,500 ° C.

All plants, animals and human beings need iron. Most iron in our body is in the red blood cells where it helps to form haemoglobin. Haemoglobin carries oxygen to all parts of our body. We also need iron in your muscles. So it’s important to eat enough food with iron in it, or else you might get tired and weak.
