Magnesium is a chemical element which we mark with Mg. Its atomic number is 12 and its mass is 24.31. Magnesium is the eighth most abundant element and constitutes about 2% of the Earth's crust by weight, and it is the third most plentiful element dissolved in seawater. But magnesium is a metal which can't be find out like free element in the nature. Many of our living cells include and live with magnesium compounds. Products from magnesium are different alloys and supplements, magnesium oxide, magnesium hydroxide and others. Magnesium is not found on its own in nature due to its reactivity. It can be found however in the forms of sulphates, carbonates, and silicates. It is an important element for both plants and animals. Magnesium is a light, silvery-white, and fairly tough metal. It tarnishes slightly in air, and finely divided magnesium readily ignites upon heating in air and burns with a dazzling white flame. It is non-toxic, has excellent machining qualities, and exhibits a capacity to dampen and absorb vibration and electromagnetic waves.
The name of the element magnesium came from Magnesia - a Greece city where large deposits of magnesium carbonate were discovered in ancient times. The first discover was J. Black who found it in 1755. More information we can introduce you in our history section.
Magnesium is the lightest of all structural metals. As such, it forms the basis for commercial alloys that have found successful use in a wide variety of applications. Although magnesium doesn't occur in the nature in the metallic form, magnesium compounds occur all over the world, and there are commercial amounts of magnesium ores in most countries.


What is magnesium?

Green vegetables such as spinach provide magnesium because the center of the chlorophyll molecule contains magnesium. Nuts (especially cashews and almonds), seeds, and some whole grains are also good sources of magnesium.

Notable features

Magnesium is a fairly strong, silvery-white, light-weight metal. It is protected by a thin layer of oxide which is fairly impermeable and hard to remove. Magnesium reacts with water at room temperature, though it reacts much more slowly (for example) than calcium.
