Who doesn’t know iron? Do you think you know facts about Iron? Iron has been known in its pure form for at least 5,000 years. Fe is the element symbol for iron, which comes from the Latin word for iron, “ferrum”. Iron is one of the most abundant elements. About 5.6% of the earth’s crust and almost all of the earth’s core is comprised by iron.
Iron has many benefits in everyday life. That includes our bodies. In this article we will outline the facts about iron. Some of these facts you may have just found out. Here are the facts about the iron:
Knowing More Facts About Iron
Iron is essential for human life. Iron is used to make strong buildings, fences, and much more. Ancient iron was often used to make swords and shields that were used for warfare. No wonder the blacksmith profession was in demand by many people.
The chemical element iron has the symbol Fe with its atomic number 26 and is a transition metal. Iron is the 4th most common element in the earth’s crust, about 5% of which is usually found as iron oxide in minerals such as hematite.
Iron is a metal that is relatively inexpensive and can be used as a raw material for most equipment. Today, machines, vehicles and many building structures are made of iron. This element is hard but can be hammered into various forms.
Not only as a raw material for the manufacture of many tools, iron is also present in the body and has many important functions. The importance of iron in the body so that iron deficiency can cause weakness and fainting.
Lack of iron can also cause disruption of the brain’s ability to remember (memory) and mental function in adolescents. According to one study, pregnant women who do not get enough iron nutrition are at risk of giving birth to babies with small weights.
Animals and plants also need iron. Plants use iron in chlorophyll, a pigment used in photosynthesis. Humans and some animals use iron in the hemoglobin molecule in the blood to allow the transport of oxygen to tissues throughout the body.
You can consume certain foods that contain iron to meet your daily iron needs. Iron-rich foods such as red meat, fish, tofu, beans and green beans. As an adult, your need for iron is only 18 mg per day. Meanwhile, pregnant women need more iron, namely 27 mg per day.
Excess iron can lead to iron poisoning. Symptoms include vomiting, diarrhea, abdominal pain, restlessness, drowsiness, rapid breathing, palpitations, fainting, seizures, and low blood pressure. In the next stage, the body will suffer from shock, fever, bleeding, icterus, liver failure, excess acid in the blood, which can lead to death.
Free iron in the blood reacts with peroxides to form free radicals that damage DNA, protein, lipids and other cellular components, causing disease and sometimes death. It has reached a toxic concentration of iron if the amount of iron is reached 20 milligrams of iron per kilogram of body weight, while 60 milligrams per kilogram is lethal.
Apart from iron, you may also have heard of steel. Steel is actually an alloy of iron with a little carbon or other elements. Usually very little carbon is used, which is between 0.2% to 2%. Even so, it made a huge difference especially in terms of strength.
Steel is much stronger than unmixed iron. Steel strength can reach 1000 times when compared to iron in its original form. In addition, a mixture of iron with 10.5% chromium is an ingredient used to make stainless cookware. This mixture is often referred to as stainless steel.
Have you ever seen a bicycle grille or other metal object in your house rust? The phenomenon of iron rusting can occur because iron interacts with oxygen. Iron and oxygen will react if there is water and humidity conditions. To prevent iron and steel from rusting, they can be coated with paint, plastic, or a zinc coating to remove water from the metal surface.
When iron and oxygen react in the presence of water or water vapor it forms rust (iron oxide). Corrosion is the term for rusting, which describes the disintegration of materials such as iron and steel. Because it is so easily oxidized, that iron is rarely found in the pure metal form on the earth’s surface.
Other Interesting Facts About Iron
Here are other facts about iron which we will provide in the form of key points.
- Iron has four levels of oxidation in iron compounds, namely 2, 3, 4 and 6.
- The core of the earth is thought to consist of an alloy of iron, nickel and gold.
- Saturn and Jupiter have cores that are rich in iron.
- Wrought iron used early in human history actually comes from meteors.
- Cast iron is a type of iron that contains small amounts of carbon, silicon and manganese. In ancient times cast iron was used to build structures such as cast iron bridges.
- The Iron Age is a prehistoric time when useful tools and weapons were first made of iron and steel. These dates vary in different parts of the world, with historians pointing to around the 12th century BC in ancient Greece and the 6th century BC in Northern Europe.
- In 2006, China was the largest iron producer in the world, about 33% of the world’s iron came from China.
- Machinery, vehicles and other building structures are usually constructed of iron in the form of steel.
- The greatest use of iron is to make steel, ferrous alloys and small amounts of carbon. According to archaeological records from Anatolia, humans have been producing steel for at least 4,000 years.
- Iron isn’t always magnetic! allotropic iron a (ferrous form) is ferromagnetic, however when transformed into a b allotrope, the magnet disappears even though the crystal lattice does not change.
- Iron is formed by fusion in stars that have sufficient mass. The sun and other stars contain large amounts of iron.
