Visual presentation communicates information clearly and effectively through graphical means. WikiSummarizer is a Web-based application that summarizes Wikipedia articles and presents them as Visual Summaries, Tree Views and Keyword Clouds with links to Wikipedia Knowledge Base.
WikiSummarizer is an interactive learning and teaching tool providing effective graphical visualization that reduces complex information and provides clear and attractive presentation of the essential points. The interactive summaries are easily shared and published in blogs, websites and documents as digital Visual Summaries, Tree Views and Keyword Clouds.
It is easy to collaborate and mine information using the WikiSummarizer summaries in blogs, websites, word editors, browsers, mind mapping applications, databases and content management systems.
This Visual Summary presents the keywords and the summaries of the Wikipedia article about "Magnesium". The Visual Summary map and the Keyword Cloud were automatically created by WikiSummarizer.

Wikipedia article: Magnesium
· Magnesium is the fourth most common element in the Earth as a whole (behind iron, oxygen and silicon), making up 13% of the planet's mass and a large fraction of planet's mantle.
· The relative abundance of magnesium is related to the fact that it is easily built up in supernova stars from a sequential addition of three helium nuclei to carbon (which in turn is made from three helium nuclei).
· Since magnesium is less dense than aluminium, these alloys are prized for their relative lightness and strength.
· It tarnishes slightly when exposed to air, although unlike the alkali metals, storage in an oxygen-free environment is unnecessary because magnesium is protected by a thin layer of oxide that is fairly impermeable and difficult to remove.
· Like its lower periodic table group neighbor calcium, magnesium reacts with water at room temperature, though it reacts much more slowly than calcium.
· Once ignited, it is difficult to extinguish, being able to burn in nitrogen (forming magnesium nitride), carbon dioxide (forming magnesium oxide and carbon) and water (forming magnesium oxide and hydrogen).
· Magnesium compounds are typically white crystals.
· Small amounts of dissolved magnesium ion contribute to the tartness and taste of natural waters.
· Magnesium ion in large amounts is an ionic laxative, and magnesium sulfate (common name: Epsom salt) is sometimes used for this purpose.
· So-called "milk of magnesia" is a water suspension of one of the few insoluble magnesium compounds, magnesium hydroxide.
· Magnesium hydroxide (brucite) is insoluble in water so it can be filtered out, and reacted with hydrochloric acid to obtain concentrated magnesium chloride.
· The main applications of magnesium are, in order: component of aluminium alloys, in die-casting (alloyed with zinc), to remove sulfur in the production of iron and steel, the production of titanium in the Kroll process.
· Specialty, high-grade car wheels of magnesium alloy are called "mag wheels", although the term is often more broadly misapplied to include aluminum wheels.
· Historically, magnesium was one of the main aerospace construction metals and was used for German military aircraft as early as World War I and extensively for German aircraft in World War II.
· Niche and illustrative uses of magnesium compounds Magnesium sulfate, as the heptahydrate called Epsom salts, is used as bath salts, as a laxative, and as a highly soluble fertilizer.
· Magnesium deficiency in plants causes late-season yellowing between leaf veins, especially in older leaves, and can be corrected by applying Epsom salts (which is rapidly leached), or else crushed dolomitic limestone to the soil.
· Serum magnesium levels may appear normal even in cases of underlying intracellular deficiency, although no known mechanism maintains a homeostatic level in the blood other than renal excretion of high blood levels.
· Magnesium is capable of reducing water to the highly flammable hydrogen gas: As a result, water cannot be used to extinguish magnesium fires; the hydrogen gas produced will only intensify the fire.
