Discovery: Iron has been known to humans since the ancient times, thus there is no discoverer nor date of discovery.
Iron is extremely common on Earth, and can also be found on meteorites or on other planets. The latin word "ferrum" is where iron gets the symbol Fe. The word "iron" is the Anglo-Saxon word "iren".
Use: Since ancient times, iron has been used to make weapons such as swords. Today it is one of the cheapest metals as well as the most used metal for manufacturing, as it is used to make steel alloys. Iron as a mineral is important as well, as it transports oxygen in blood through hemoglobin (which contains iron). Iron is an essential element that humans must have in their bodies in moderate amounts, too much or too little will causes diseases.
Hazards: Iron itself is not toxic or harmful and is safe for everyone, however some of its compounds could be toxic. Lacking iron in the body can cause anemia while excess iron will cause hemochromatosis, which affects the liver and kidneys. The metal power of iron is a fire hazard.
