Magnesium atomic symbol: Mg, atomic number: 12 is a Block S, Group 2, Period 3 element with an atomic mass of The number of electrons in each of Magnesium's shells is [2, 8, 2] and its electron configuration is [Ne] 3s 2.
The magnesium atom has a radius of pm and a Van der Waals radius of pm. Magnesium is the eighth most abundant element in the earth's crust and the fourth most common element in the earth as a whole.
In its elemental form, magnesium has a shiny grey metallic appearance and is an extremely reactive. It is can be found in minerals such as brucite, carnallite, dolomite, magnesite, olivine and talc. Commercially, magnesium is primarily used in the creation of strong and lightweight aluminum -magnesium alloys, which have numerous advantages in industrial applications. The name "Magnesium" originates from a Greek district in Thessaly called Magnesia.

Fact box. Glossary Image explanation Murray Robertson is the artist behind the images which make up Visual Elements. Appearance The description of the element in its natural form.
Biological role The role of the element in humans, animals and plants. Natural abundance Where the element is most commonly found in nature, and how it is sourced commercially. Uses and properties. Image explanation. The image is inspired by chlorophyll, the molecule contained in green plants that enables them to photosynthesise. Chlorophyll contains a single atom of magnesium at its centre.
A silvery-white metal that ignites easily in air and burns with a bright light. Magnesium is one-third less dense than aluminium. It improves the mechanical, fabrication and welding characteristics of aluminium when used as an alloying agent. These alloys are useful in aeroplane and car construction.
Magnesium is used in products that benefit from being lightweight, such as car seats, luggage, laptops, cameras and power tools. It is also added to molten iron and steel to remove sulfur. Magnesium sulfate is sometimes used as a mordant for dyes. Magnesium hydroxide is added to plastics to make them fire retardant. Magnesium oxide is used to make heat-resistant bricks for fireplaces and furnaces.
It is also added to cattle feed and fertilisers. Magnesium hydroxide milk of magnesia , sulfate Epsom salts , chloride and citrate are all used in medicine. Grignard reagents are organic magnesium compounds that are important for the chemical industry.
Biological role. Magnesium is an essential element in both plant and animal life. Chlorophyll is the chemical that allows plants to capture sunlight, and photosynthesis to take place.
Chlorophyll is a magnesium-centred porphyrin complex. Without magnesium photosynthesis could not take place, and life as we know it would not exist. In humans, magnesium is essential to the working of hundreds of enzymes. Humans take in about — milligrams of magnesium each day.
We each store about 20 grams in our bodies, mainly in the bones. Natural abundance. It is found in large deposits in minerals such as magnesite and dolomite. The sea contains trillions of tonnes of magnesium, and this is the source of much of the , tonnes now produced each year. It is prepared by reducing magnesium oxide with silicon, or by the electrolysis of molten magnesium chloride.
Help text not available for this section currently. Elements and Periodic Table History. The first person to recognise that magnesium was an element was Joseph Black at Edinburgh in He distinguished magnesia magnesium oxide, MgO from lime calcium oxide, CaO although both were produced by heating similar kinds of carbonate rocks, magnesite and limestone respectively.
Another magnesium mineral called meerschaum magnesium silicate was reported by Thomas Henry in , who said that it was much used in Turkey to make pipes for smoking tobacco. An impure form of metallic magnesium was first produced in by Anton Rupprecht who heated magnesia with charcoal. A pure, but tiny, amount of the metal was isolated in by Humphry Davy by the electrolysis of magnesium oxide.
However, it was the French scientist, Antoine-Alexandre-Brutus Bussy who made a sizeable amount of the metal in by reacting magnesium chloride with potassium, and he then studied its properties. Atomic data. Glossary Common oxidation states The oxidation state of an atom is a measure of the degree of oxidation of an atom.
It is not easy to split up a compound into its elements - the only way to do this is in chemical reactions. Chemical formulae of compounds A compound is a substance that contains two or more elements that are chemically combined. The formula shows: the symbols for each element in the compound the number of atoms of each element in a unit of the compound For example, magnesium oxide is made up of two elements, magnesium and oxygen. In compounds made up of non-metal elements only, the second word of the compound's name starts with mon-, di-, or tri-, eg carbon dioxide.
This shows the number of atoms of this element for every one atom of the first element in the name. So for carbon dioxide there are two oxygen atoms for every carbon atom. Related audio.
