At room temperature, magnesium is a solid that is an alkaline earth metal. Magnesium is a member of group 2 on the periodic table. Its atomic number is 12, and its atomic weight is 24.305 grams/mol.
Magnesium has the chemical symbol Mg and a density of 1.74 grams per cubic centimeter. It is silvery-white in color, malleable and ductile.
Magnesium’s name originates from a region called Magnesia in Greece, where there was an abundance of ore containing this element. Magnesium is not found in nature in its pure state, but it is present in ores, such as dolomite and carnallite. It is also found in seawater.
Applications of magnesium and its compounds include uses in the pharmaceutical industry, pyrotechnics, photography and lightweight aircraft parts.Learn More
