There are over 60 minerals in which magnesium is found. Brucite, carnallite, dolomite, magnesite, olivine and talc are the important commercial ones. Note that magnesium can also be produced from magnesium-containing compounds recovered from brines, sea water and from wells. Links are provided to the relevant Wikipedia articles.
The name 'Magnesium' originates from the Greek word for a district in Thessaly called Magnesia. It is related to magnetite and manganese, which also originated from this area, and required differentiation as separate substances.
Magnesium is the seventh most abundant element in the Earth's crust by mass and eighth by molarity. It is found in large deposits of magnesite, dolomite, and other minerals, and in mineral waters, where magnesium ion is soluble. In 1618 a farmer at Epsom in England attempted to give his cows water from a well. They refused to drink because of the water's bitter taste. However the farmer noticed that the water seemed to heal scratches and rashes. The fame of Epsom salts spread. Eventually they were recognized to be hydrated magnesium sulfate, MgSO4.
The metal itself was first produced in England by Sir Humphry Davy in 1808 using electrolysis of a mixture of magnesia and HgO. A. A. B. Bussy prepared it in coherent form in 1831. Davy's first suggestion for a name was magnium, but the name magnesium is now used.
Magnesium ores such as Magnesite MgCO3 and Dolomite MgCO3.CaCO3 , are the main constituents of earth crust so they exist in almost all the Sedimentary rocks on earth and beneath the earth surface.
In nature, you could find it in sea water, magnesite, and dolomite.
Magnesium can be found in large amounts in the ocean - However it is found as a compound (not sure which... :/ ) and must be refined.

Will lead react with magnesium sulphate?
Lead will not react with magnesium sulfate because lead is less reactive than magnesium. Magnesium will displace lead in a single displacement reaction, but in the case of magnesium sulfate, there is no driving force for the reaction to occur.
Is magnesium soft?
Yes, magnesium is a lightweight metal that is soft and can be easily cut with a knife.
How will you find the valency of chlorine sodium and magnesium?
Look in the periodic table at groups; sodium has the valence +1, magnesium +2 and chlorine -1.
Where to find magnesium?
Magnesium can be found in foods such as nuts, seeds, whole grains, leafy green vegetables, and legumes. It is also available as a dietary supplement in various forms including magnesium oxide, citrate, and glycinate.
How do you calculate moles of atoms in 9.00g of magnesium nitrate?
First, determine the molar mass of magnesium nitrate (Mg(NO3)2) by adding the atomic masses of magnesium, nitrogen, and oxygen. Then, divide the given mass (9.00g) by the molar mass to find the moles of magnesium nitrate.
What is the atomic number for isotope magnesium-125?
We can find Magnesium as a metal element. Atomic number of it is 12.
How do you find the melting point of magnesium?
650.0 °CGoogle it...

What is the common name of Magnesium Chloride?
The common name of Magnesium Chloride is simply magnesium chloride.
What is the molarity of 48.6 grams of magnesium?
To find the molarity of 48.6 grams of magnesium, you first need to determine the number of moles of magnesium in 48.6 grams using the molar mass of magnesium (24.305 g/mol). Then, you divide the moles of magnesium by the volume of the solution in liters to get the molarity.
Can you calculate the number of moles of magnesium used grams permol?
To calculate the number of moles of magnesium used, you divide the mass of magnesium by its molar mass. The molar mass of magnesium is approximately 24.31 g/mol. For example, if you have 12.15 grams of magnesium, you would divide 12.15 by 24.31 to find that you have 0.5 moles of magnesium.
How will you find the valency of chlorine sodium and magnesium?
Look in the periodic table at groups; sodium has the valence +1, magnesium +2 and chlorine -1.
Why did man kind find gold be for magnesium?
Gold is much lower down in the reactivity series for metals, whereas magnesium is higher up and hence more reactive. Being more reactive, the chances are that the magnesium will have reacted and formed a compound such as magnesium oxide.
What is the aim of the burning magnesium experiment?
The aim of the burning magnesium experiment is to demonstrate the intense, bright white light produced when magnesium metal combusts in air. The experiment is often used to showcase the principle of combustion and the high reactivity of magnesium with oxygen.
Where can people find a list of foods that are high in magnesium?
People can find a list of foods that are high in magnesium from the internet or from their doctor. Some foods include whole grains, nuts, and green leafy vegetables.
Magnesium oxide decomposes into magnesium and oxygen If 4.03 of magnesium oxide decomposes to form 2.43 of magnesium what mass of oxygen gas is also released in the reaction?
To find the mass of oxygen gas released, you need to calculate the mass of magnesium oxide that contributed to the formation of 2.43g of magnesium. Molar mass of MgO = 40.3g/mol Molar mass of Mg = 24.3g/mol Calculate the moles of Mg formed and use stoichiometry to find the moles of oxygen reacted. Finally, convert the moles of O2 to grams to find the mass of oxygen gas released.
