From Webster's Revised Unabridged Dictionary (1913) [web1913]:
Magnesium \Magne"sium\, n. [NL. & F. See {Magnesia}.] (Chem.) A light silver-white metallic element, malleable and ductile, quite permanent in dry air but tarnishing in moist air. It burns, forming (the oxide) magnesia, with the production of a blinding light (the so-called magnesium light) which is used in signaling, in pyrotechny, or in photography where a strong actinic illuminant is required. Its compounds occur abundantly, as in dolomite, talc, meerschaum, etc. Symbol Mg. Atomic weight, 24.4. Specific gravity, 1.75. {Magnesium sulphate}. (Chem.) Same as {Epsom salts}.
From The Elements (22Oct97) [elements]:
magnesium Symbol: Mg Atomic number: 12 Atomic weight: 24.312 Silvery metallic element belonging to group 2 of the periodic table (alkaline-earth metals). It is essential for living organisms, and is used in a number of light alloys. Chemically very reactive, it forms a protective oxide coating when exposed to air and burns with an intense white flame. It also reacts with sulphur, nitrogen and the halogens. First isolated by Bussy in 1828.
