explain the iron in science
Answers
Answer:
Iron (/ˈaɪərn/) 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. ... However, iron reacts readily with oxygen and water to give brown to black hydrated iron oxides, commonly known as rust.
Explanation:
Iron is the most common element found in largely in outer as well inner core of the earth.
The symbol of iron is ‘Fe’ and atomic number is ‘26.’
Iron is one of the earliest known elements that is being used by human beings.
Salient Features of Iron
Following are the major features of iron −
Pure iron element is soft, ductile, and malleable.
The boiling point of iron ranges between 15330C and 24500C.
Iron easily gets attracted towards magnet.
In dry air, iron remains inactive and does not react (with air); however, in moist air, it reacts and forms rust.
Pure iron normally does not react with pure water; however, it reacts easily with ordinary of polluted water and rust forms.
Iron reacts with halogen and Sulphur to form halide and sulphide accordingly.
Occurrence of Iron
The inner and outer cores of the earth are largely made up of iron and nickel.
Most likely, iron is the most abundantly available element of the earth; however, it is the fourth most abundantly available element of the crust.
Types of Iron
Following are the major types iron −
Hematite - Fe2O3
Magnetite - Fe3O4
Siderite - FeCO3

Uses of Iron
Among all the metals, iron is most widely used (about 90 percent of world’s total metal production).
In most of the heavy industries, iron is the most essential element.
Industries like railway, ship building, automobile, engineering construction, etc., everywhere, iron is essentially required.
