On this page I'll provide comprehensive data for Magnesium. I hope you profit from it.
Magnesium Overview
Name Origin
From Magnesia ancient city in district of Thessaly, Greece.
Symbol
Mg (Magnesium)Description
Lightweight, malleable, silvery-white metal. Eighth most abundant element in the universe. Seventh most abundant element in the earth's crust.
Discovery
Discovered By: Sir Humphrey Davy
Year: 1808
Location: England
Sources
Usually obtained by electrolysis of melted magnesium chloride (MgCl2) found in sea water. Each cubic mile of seawater contains about 12 billion pounds of magnesium.
Uses
Used in alloys to make airplanes, missiles and other uses for light metals. Has structural properties similar to aluminium. But since it is flammable at temperatures of burning gasoline, its uses are limited.
State at 20 °C
