Alkaline earth metal

alkaline earthalkaline earth metalsgroup 2
It is a shiny gray solid which bears a close physical resemblance to the other five elements in the second column (group 2, or alkaline earth metals) of the periodic table: all group 2 elements have the same electron configuration in the outer electron shell and a similar crystal structure. It tarnishes slightly when exposed to air, although, unlike the heavier alkaline earth metals, an oxygen-free environment is unnecessary for storage because magnesium is protected by a thin layer of oxide that is fairly impermeable and difficult to remove.
They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).

Symbol (chemistry)

Magnesium is a chemical element with the symbol Mg and atomic number 12.

Magnesium oxide

magnesiaMgOmagnesia alba
Once ignited, such fires are difficult to extinguish, because combustion continues in nitrogen (forming magnesium nitride), carbon dioxide (forming magnesium oxide and carbon), and water (forming magnesium oxide and hydrogen). Magnesium forms a variety of compounds important to industry and biology, including magnesium carbonate, magnesium chloride, magnesium citrate, magnesium hydroxide (milk of magnesia), magnesium oxide, magnesium sulfate, and magnesium sulfate heptahydrate (Epsom salts).
Magnesium oxide (MgO), or magnesia, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of magnesium (see also oxide).

Adenosine triphosphate

ATPadenosine triphosphate (ATP)adenosine 5'-triphosphate
Magnesium ions interact with polyphosphate compounds such as ATP, DNA, and RNA.
The binding of a divalent cation, almost always magnesium, strongly affects the interaction of ATP with various proteins.

Magnalium

The metal is now obtained mainly by electrolysis of magnesium salts obtained from brine, and is used primarily as a component in aluminium-magnesium alloys, sometimes called magnalium or magnelium.
Magnalium is an aluminium alloy with 5% magnesium and 95% aluminum.

Aluminium

The metal is now obtained mainly by electrolysis of magnesium salts obtained from brine, and is used primarily as a component in aluminium-magnesium alloys, sometimes called magnalium or magnelium.
The only lighter metals are the metals of groups 1 and 2, which apart from beryllium and magnesium are too reactive for structural use (and beryllium is very toxic).

Phenylmagnesium bromide

Examples of Grignard reagents are phenylmagnesium bromide and ethylmagnesium bromide.
Phenylmagnesium bromide, with the simplified formula, is a magnesium-containing organometallic compound.

Thermite

Thermite grenadesThermitM-50
Magnesium may also be used as an igniter for thermite, a mixture of aluminium and iron oxide powder that ignites only at a very high temperature.
Fuels include aluminium, magnesium, titanium, zinc, silicon, and boron.

Magnesium injection cycle

magnesium-based engine
Magnesium's reversible reaction with water can be harnessed to store energy and run a magnesium-based engine.
Magnesium Injection Cycle (MAGIC) is an engine design under development by Mitsubishi Corporation and the Tokyo Institute of Technology that uses magnesium and water to generate power.

Magnesite

magnasite
It is found in large deposits of magnesite, dolomite, and other minerals, and in mineral waters, where magnesium ion is soluble.
Magnesite is a mineral with the chemical formula MgCO 3 (magnesium carbonate).

Dolomite is an anhydrous carbonate mineral composed of calcium magnesium carbonate, ideally CaMg(CO 3 ) 2.

Magnesium nitride

Mg 3 N 2 MgZn 2
Once ignited, such fires are difficult to extinguish, because combustion continues in nitrogen (forming magnesium nitride), carbon dioxide (forming magnesium oxide and carbon), and water (forming magnesium oxide and hydrogen).
Magnesium nitride, which possesses the chemical formula Mg 3 N 2, is an inorganic compound of magnesium and nitrogen.

Carnallite

Although magnesium is found in more than 60 minerals, only dolomite, magnesite, brucite, carnallite, talc, and olivine are of commercial importance.
Carnallite (also carnalite) is an evaporite mineral, a hydrated potassium magnesium chloride with formula KMgCl 3 ·6(H 2 O).

Tarnish

It tarnishes slightly when exposed to air, although, unlike the heavier alkaline earth metals, an oxygen-free environment is unnecessary for storage because magnesium is protected by a thin layer of oxide that is fairly impermeable and difficult to remove.
Tarnish is a thin layer of corrosion that forms over copper, brass, silver, aluminum, magnesium, neodymium and other similar metals as their outermost layer undergoes a chemical reaction.

Brucite

Although magnesium is found in more than 60 minerals, only dolomite, magnesite, brucite, carnallite, talc, and olivine are of commercial importance.
Brucite is the mineral form of magnesium hydroxide, with the chemical formula Mg(OH) 2.

Aluminium alloy

As of 2013, magnesium alloys consumption was less than one million tonnes per year, compared with 50 million tonnes of aluminum alloys.
The typical alloying elements are copper, magnesium, manganese, silicon, tin and zinc.

Flash (photography)

Later, magnesium filament was used in electrically ignited single-use photography flashbulbs.
Studies of magnesium by Bunsen and Roscoe in 1859 showed that burning this metal produced a light with similar qualities to daylight.

RNA

Magnesium ions interact with polyphosphate compounds such as ATP, DNA, and RNA.
Since RNA is charged, metal ions such as Mg 2+ are needed to stabilise many secondary and tertiary structures.

Firebombing

This property was used in incendiary weapons during the firebombing of cities in World War II, where the only practical civil defense was to smother a burning flare under dry sand to exclude atmosphere from the combustion.
There were two types of incendiary bombs: those made of magnesium and iron powders, and those made of petroleum.

Manganese

Sufficient manganese overcomes the corrosive effects of iron.
Historically, manganese is named for pyrolusite and other black minerals from the region of Magnesia in Greece, which also gave its name to magnesium and the iron ore magnetite.
