Definition of iron

(Entry 1 of 3) 1 : a silver-white malleable ductile magnetic heavy metallic element that readily rusts in moist air, occurs in pure form in meteorites and combined in most igneous rocks, is the most abundant element on Earth by mass, and is vital to biological processes — see Chemical Elements Table.

What is iron short answer?

Iron is a brittle, hard substance, classified as a metal in Group 8 on the Periodic Table of the Elements. The most abundant of all metals, its pure form rapidly corrodes from exposure to moist air and high temperatures.

Where is iron used?

It is used in architecture, bearings, cutlery, surgical instruments and jewellery. Cast iron contains 3–5% carbon. It is used for pipes, valves and pumps. It is not as tough as steel but it is cheaper.

  • Medical – surgical stainless steel, implantable devices.

Where do you find iron?

It is found in animal foods that originally contained hemoglobin, such as red meats, fish, and poultry (meat, poultry, and seafood contain both heme and non-heme iron). Your body absorbs the most iron from heme sources. Most nonheme iron is from plant sources.

What are properties of iron?

Iron is a lustrous, ductile, malleable, silver-gray metal (group VIII of the periodic table). It is known to exist in four distinct crystalline forms. Iron rusts in damp air, but not in dry air. It dissolves readily in dilute acids.

Iron is used to make alloy steels like carbon steels with additives such as nickel, chromium, vanadium, tungsten, and manganese. These are used to make bridges, electricity pylons, bicycle chains, cutting tools and rifle barrels. Cast iron contains 3–5% carbon. It is used for pipes, valves, and pumps.

Why iron is a metal?

Iron is called metal because it is malleable and ductile and has high density and hard.

How is iron formed?

Today, iron is made by heating hematite or magnetite in a blast furnace along with with a form of carbon called “coke” as well as calcium carbonate (CaCO3), better known as limestone. This yields a compound that contains about 3 percent carbon and other adulterants – not ideal in quality, but good enough to make steel.

Who discovered the iron?

Archeologists believe that iron was discovered by the Hittites of ancient Egypt somewhere between 5000 and 3000 BCE. During this time, they hammered or pounded the metal to create tools and weapons. They found and extracted it from meteorites and used the ore to make spearheads, tools and other trinkets.

How much iron is in the human body?

Males of average height have about 4 grams of iron in their body, females about 3.5 grams; children will usually have 3 grams or less. These 3-4 grams are distributed throughout the body in hemoglobin, tissues, muscles, bone marrow, blood proteins, enzymes, ferritin, hemosiderin, and transport in plasma.

Is iron a strong metal?

Iron – One of the components of steel, and the go-to metal for tool and weapon makers throughout the ages, iron completes the list of the world’s strongest metals. Cast iron scores about 5 on the Mohs scale, and its yield and tensile strengths are about 246 and 414 Mpa respectively.

What is iron color?

Iron is a metallic element that has a silver color and reflective appearance in its pure form. Iron is highly reactive such that it easily turns red, orange or black when exposed to oxygen. Many alloys of iron, such as steel or stainless steel, are silver.

How many types of iron are there?

There are two types: heme iron and non-heme iron. Heme iron is found in meats, especially in red meat and in organ meat like liver, which stores excess iron in humans and other animals. Non-heme iron, on the other hand, is found in beans, lentils, spinach, kale and apricots, to name a few sources.

Why the blood is red in colour?
