BackgroundThe first to discover the element Magnesium was Joseph Black, a Scottish physician and chemist, in the year 1755. The name Magnesium was derived from the the Greek city Magnesia.Magnesium is the 3rd most commonly used structured metal and is extremely light. Because of its low weight and good mechanical and electrical properties, it is commonly used for manufacturing cellphones, laptops, cameras, and other portable electronics. Magnesium also is used in flares, fireworks, and sparklers because it ignites easily and burns with a bright light that is relatively non-toxic.
Physical Properties
  • State of matter at room temperature: Solid
  • Melting Point: 650°C
  • Boiling Point: 1090°C
  • Density: 1.74 g/mL
  • Abundance in Earth's crust: about 23,300 ppm

Chemical Properties
  • Other elements that will react with Magnesium: Magnesium submerged in room temperature water (H2O) will produce hydrogen bubbles on the surface of the metal (reactions occurs faster with higher temperatures).
  • Compounds that contain Magnesium: Magnesium oxide (MgO) is the second most common compound in the Earth's crust, also abundant in beach sand. Magnesium chloride (MgCl2) i found in seawater.
  • Magnesium is essential for humans as well as for plants. Many enzymes, including the ones that utilize and synthesize ATP, need magnesium ions for their catalytic actions. In addition to that, plants also need it since magnesium is part of the chlorophyll. Also, it competes with calcium, keeping calcium in check. Although Human magnesium deficiency is very rare, it can be associated with the development of several illnesses such as asthma and diabetes. However, with the healthy intake, magnesium can help prevent stroke and heart attack, and migraines and premenstrual syndrome are less severe.
