magnesium, Mg, atomic number 12(noun)
a light silver-white ductile bivalent metallic element; in pure form it burns with brilliant white flame; occurs naturally only in combination (as in magnesite and dolomite and carnallite and spinel and olivine)
A light, flammable, silvery metal, and a chemical element (symbol Mg) with an atomic number of 12.
Origin: From magnesium, from .
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
Origin: [NL. & F. See Magnesia.]
Magnesium is a chemical element with the symbol Mg and atomic number 12. Its common oxidation number is +2. It is an alkaline earth metal and the eighth most abundant element in the Earth's crust and ninth in the known universe as a whole. Magnesium is the fourth most common element in the Earth as a whole, making up 13% of the planet's mass and a large fraction of the planet's mantle. The relative abundance of magnesium is related to the fact that it easily builds up in supernova stars from a sequential addition of three helium nuclei to carbon. Due to magnesium ion's high solubility in water, it is the third most abundant element dissolved in seawater. The free element is not found naturally on Earth, as it is highly reactive. The free metal burns with a characteristic brilliant white light, making it a useful ingredient in flares. The metal is now mainly obtained by electrolysis of magnesium salts obtained from brine. Commercially, the chief use for the metal is as an alloying agent to make aluminium-magnesium alloys, sometimes called magnalium or magnelium. Since magnesium is less dense than aluminium, these alloys are prized for their relative lightness and strength.
Chambers 20th Century Dictionary
mag-nē′shi-um, or -si-um, n. a metal of a bright, silver-white colour, which while burning gives a dazzling white light, and forms magnesia.—n. Magnē′sia, a light white powder, got by burning magnesium, used as a medicine.—adj. Magnē′sian, belonging to, containing, or resembling magnesia.—n. Mag′nesite, native magnesium carbonate.
