Iron is the 4th most abundant element in the Earth's crust. The Earth's core is believed to be comprised primarily of iron. Pure iron is chemically reactive and corrodes rapidly, especially in moist air or at elevated temperatures. There are four allotropes of iron known as 'ferrites'.
Iron (/ ˈ aɪ ər n /) is a chemical element with symbol Fe (from Latin: ferrum) and atomic number 26. It is a metal, that belongs to the first transition series and group 8 of the periodic table.It is by mass the most common element on Earth, forming much of Earth's outer and inner core.It is the fourth most common element in the Earth's crust.. Pure iron is very rare on the Earth's cru...
A horizontal row in the periodic table. The atomic number of each element increases by one, reading from left to right. Block Elements are organised into blocks by the orbital type in which the outer electrons are found. These blocks are named for the characteristic spectra they produce: sharp (s), principal (p), diffuse (d), and fundamental (f).
Iron is also found in the cores of all of the planets in the Solar System. Iron is the heaviest element formed in the cores of stars, according to JPL. Elements heavier than iron can only be ...
Source: Iron is not found free in nature but is found in iron ores such as hematite (Fe 2 O 3), magnetite (Fe 3 O 4) and taconite. Commercially, iron is produced in a furnace at temperatures of about 2000 o C by the reduction of hematite or magnetite with carbon. Isotopes: Iron has 24
Iron also makes up about 5% of the Earth's crust where it is the fourth most abundant element. Because iron oxidizes when it comes into contact with air, most of the iron that is found on the surface of the Earth is in iron oxide minerals such as hematite and magnetite. Iron is also found in meteorites which can sometimes contain a large ...
There is a whole period of time named after this element (Iron Age). Humans have been working with iron for thousands of years. Iron is found all over the Earth and the Universe. You have iron in your computer, your desk, and even your body. When purified, iron is a grayish, shiny metal.
Archaeological evidence suggests that people have been using iron for at least 5000 years. Iron is the cheapest and one of the most abundant of all metals, comprising nearly 5.6% of the earth's crust and nearly all of the earth's core. Iron is primarily obtained from the minerals hematite (Fe 2 O 3) and magnetite (Fe 3 O 4).
Iron is an ancient element that has no specific date of discovery and no scientist to credit with its detection. The use of iron dates back to the Egyptians, who used it prior to 3400 B.C. The Bible mentions iron several times. Pliny the Elder, a historian who wrote in the first century A.D., noted that iron was used in houses and weapons of ...
Iron can also be found in myoglobin which takes oxygen from hemoglobin and holds it in the muscles until it is needed. Iron is present in meat and vegetables, but the human body absorbs iron faster from animal products than plants. Not having enough iron in the body can cause iron deficiency which can lead to anemia.
