Magnesium Facts: 11-15 | Characteristics of Magnesium
11. One of the most interesting Magnesium facts is the outermost shell of its atom has only two electrons, making it highly reactive. This explains why Magnesium is not available as an independent element in nature. It is found in form of some chemical compounds such as Magnesium chloride.
12. Because of its atomic structure and its highly reactive nature, leaving pure Magnesium in air will make it react with air. A corrosive reaction takes place just as in case of iron (which reacts with air to form rust). This corrosive reaction leads to formation of Magnesium oxide. This Magnesium oxide forms a thin layer on the element and prevents it from further corrosion.
13. Both Magnesium and its various alloys are known for high corrosion resistance (thanks to formation of Magnesium oxide). They are also known for high temperature mechanical properties.
14. Magnesium is a light-weight and low-density element. It’s density is only 2/3rd of Aluminum. Magnesium is also a malleable element. This means, it can be beaten with hammer to form a thin sheet without breaking or cracking it.
15. At room temperature, Magnesium will react with water but very slowly. However, if temperature is increased, reaction between Magnesium and water will be faster.
Magnesium Facts: 16-20 | Magnesium Fun Facts and Uses
16. Magnesium can be ignited. However, it can be ignited easily if it is in powder form or in thinly shaved form. If Magnesium is in form of a large mass or chunk, it is difficult to ignite the metal. Once ignited, Magnesium burns with a very bright white flame.
17. It is very difficult to extinguish ignited Magnesium. Attempting to extinguish ignited Magnesium with water will only intensify the fire because it reacts with water to form hydrogen, which in turn is a flammable element (gas) and hence, worsens the situation.
18. If one attempts to extinguish ignited Magnesium using pure carbon dioxide or pure nitrogen, that will also cause problems because the element is known to burn in both pure CO2 and pure nitrogen. The best way to put off or extinguish an ignited Magnesium is to cover it with sand or to use dry chemical fire extinguisher.
19. Because Magnesium burns to form a brilliant light, it is widely used in flares, photography and pyrotechnics.
20. Magnesium has a sour taste. The slightly sour flavor of the mineral water we drink comes from the little amounts of Magnesium added in the water.
