Terence Bell wrote about commodities investing for The Balance, and has over 10 years experience in the rare earth and minor metal industries. Magnesium's characteristics are similar to its sister metal aluminum. Learn more about Magnesium uses, effectiveness, possible side effects, interactions, dosage, user ratings and products that contain Magnesium Hundreds of enzymes thus require magnesium ions to function. Magnesium anodes also generally produce more theoretical amp hours per pound of magnesium and the number of theoretical pounds that are used per year is less than that of zinc anodes. Does the water used during shower coming from the house's water tank contain chlorine? Is Magnesium Dangerous.. by: Kerri Knox, RN- The Immune Queen! magnesium definition: 1. a chemical element that is a silver-white metal. Other uses for magnesium are as an anode for cathodic protection in chemical storage tanks, pipelines, and ships, and in the production of flare bombs, incendiary bombs, and fireworks. It is an alkaline earth metal and the eighth most abundant element in the Earth's crust[2] and ninth in the known universe as a whole. Hi Norma, Can you tell me exactly what part of the danger of magnesium that you are referring to? Magnesium is a chemical element with the symbol Mg and atomic number 12. Magnesium has a high strength-to-weight ratio, it is dent and impact resistant, it has immense damping capacity, and it maintains a low inertia. Source: http://minerals.usgs.gov/minerals/pubs/commodity/magnesium/, The International Magnesium Association. Elemental magnesium is a gray-white lightweight metal, two-thirds the density of aluminium. Depending upon the location and type of resource being used, a wide variety of production methods can be used to refine magnesium metal.
