What are the properties of magnesium?
Magnesium is a chemical element that requires all living cells of all known organisms. When the elements in the Earth's crust are measured with matter, magnesium is the most common eighth. In sea water it is the third most common. Magnesium properties lead to its use in components of trucks and cars such as Mag Wheels. The name for magnesium comes from the ancient Greek district of Magnesia. It creates a metal and is part of a group known as metals of the alkaline country, elements of the periodic table that contains group 2. Water cannot be used because magnesium responds to the formation of hydrogen gas, which is highly burning. The only way to extinguish this type of fire is to suffocate it under sand or use a dry chemical fire extinguisher. This feature of magnesium has led to use in the bombing of cities in World War II.
powder created by magnesium is used in marine lights and for the production of pyrotechnics. In the first days of the photo with pIt uses to create a brilliant white light. Magnesium flames can reach 2500 ° F (1,371 ° C). For this metal there are a number of other practical uses, including combinations in zinc, aluminum or manganese for the production of air components, racing bikes and missiles.
people require magnesium for more than 300 biochemical reactions, including those that create DNA and RNA. The deficiency in the human diet is relatively common, maybe leads to diseases such as osteoporosis and asthma. About half of the magnesium of the body is located in the base. Green leafy vegetables are a good diet source of magnesium. Other sources include cereals, coffee, cocoa, tea, nuts and spices.
Magnesium has an atomic mass of 24.3 and in the period table is 12. The physical properties of magnesium include the melting point of 1202 ° F (650 ° C) and boiling point 1994 ° F (1091 ° C). This high melting point leads to the magnesium to remain a solid in fires. His crystals are hexagonal. The density is 1.74 g/cm3 that is low in comparisonWith other metals such as aluminum.
The chemical properties of magnesium tend to respond with halogens such as chlorine to form ionic salts. Magnesium has two electrons in its farthest cloak, which gives it an oxidation state of +2. The loss of these two electrons to form a stable ion compound is vigorously favorable, so that the magnesium is generally found as salt. Such a reaction is the reaction of magnesium with chlorine in seawater to form MGCL 2 .
Salts of Magnesium has many uses, especially magnesium sulfate, mgso 4 . Magnesium sulfate properties include the tendency to absorb water from the air. This makes it useful as a drying agent. Such magnesium sulfate is known as anhydrous or lacks water.
magnesium sulfate is naturally found in mineral bearings and is used medically in hydrated form, which means it is associated with water molecules. For example, Epsom salt is MGSO 4 .7H 2 O. Significant medical use would beLO reduction of eclampsia in pregnant women. In rare cases, excessive magnesium consumption from laxatives and antacids may be toxic.
plants require magnesium because it is in the center of the chlorophyll molecules used in photosynthesis. To ensure that the plants have enough of this element, the magnesium sulphate often uses as a plant fertilizer. The high solubility of magnesium sulfry gives it an advantage over other types of magnesium fertilizers.
