The melting point of magnesium is 649 degrees Celsius or 1200 degrees Fahrenheit.
Magnesium was first recognized as an element in 1755 by Joseph Black from Edinburgh, Scotland. Sir Humphrey Davy, however, was the one who first isolated it in 1808.
Today magnesium is an important mineral in everything from products that are used around the home to the overall health and well-being of a person. In fact, the world produces around 350,000 tons of magnesium each year. Most of the world’s magnesium is obtained by the electrolysis of melting magnesium chloride, which is found in seawater. It is also mined in areas of Austria, China, Poland, United States, Canada, India, Greece, and Russia. Magnesium has a grayish white appearance. It is a metal that reacts with hot water and will burn in air when it is ignited. Magnesium is used as an alloy in the construction and manufacturing of airplanes, missiles, racing bikes, filters, pigments, fireplace bricks, and flashbulbs. The atomic structure of magnesium is made up of twelve electrons, twelve protons, and twelve neutrons.
When it comes to health care, magnesium is responsible for over 300 functions within the human body. This mineral is responsible for helping to maintain normal muscle and nerve functions, helps to keep the immune system strong, it works to keep a steady rhythm in the heart, and makes bones strong. In fact, over one percent of the magnesium that is found within the human body is located in the blood alone.
Quote: “Sodium, magnesium and aluminium are all metals. They have metallic bonding, in which positive metal ions are attracted to delocalised electrons. Going from sodium to aluminium: the charge on the metal ions increases from +1 to +3 (with magnesium at +2); the number of delocalised electrons increases; so the strength of the metallic bonding increases; the melting points and boiling points increase.”
