Magnesium is the twelfth element on the periodic table. It is located in the second group called the alkaline earth metals. Natural magnesium contains three different isotopes, and there are twelve others that are recognized. Seawater is a rich source of magnesium in the form of salt. Magnesium is the eighth most abundant element in the earth’s crust.
Magnesium readily ignites upon heating in air and burns with a dazzling white flame. To extinguish the flame water should not be used. Alkaline earth metal salts in general, are less soluble in water than the corresponding alkali metal salts. Some are even so insoluble that they resist weathering and leaching action in rainwater.
Alkaline earth metals are extracted from the mineral ores like they have been for many decades. This second group of metals is also less reactive than the alkali metals. They do not need to have a specific storage procedure like that of the corresponding elements. These alkaline metals react with acids, and in certain temperatures of water. They are also harder than their alkali friends.
In general, they have a gray-white luster that tarnishes quickly in the air to form a tough, thin oxide coating. The coating protects the metal, particularly magnesium, from further oxidation. This allows alloys of these metals to be used as low-density structural materials. Magnesium is one of the two most important alkaline earth metals.

The tested elements are sodium, lithium, potassium and calcium and each of them were placed in a beaker filled with water. The resulting solutions pH levels were tested with ...
It is found in seawater. Today, though it is chiefly produced by electrolysis of fused magnesium chloride. It has many uses. Magnesium is an important material that is a chief component in a number of high-tensile-strength, low-density alloys. These properties allow the alloy to be very valuable in air and spacecraft construction. Also, the alloyed metal is used to make a large variety of other products such as, artificial limbs, vacuum cleaners, optical instruments, recreational skis, wheelbarrows, lawn mowers, and outdoor furniture.
Magnesium is also found in asbestos. Asbestos was used in insulating materials up until it was found to cause cancer and other types of lung diseases. The unalloyed metal of magnesium is used in photographic flashlight powders, incendiary bombs, and signal flares. This special element also has many important roles in the body. The most vital need for it is on the cellular level. It is as important as calcium, and is found in bones, blood and soft tissues.
Magnesium is essential for strong healthy bones and teeth. In the environment, magnesium reduces carbon monoxide, carbon dioxide, sulfur dioxide, nitric acid, and nitrous oxide. All of which are relatively harmful to the body or the environment. First discussing the alloyed metal, one can see its many uses on an everyday basis.
Look in the sky, do you see any type of aircraft It was made from the alloyed metal of magnesium. There are advantages to using magnesium for die castings. It is better than most metals in many circumstances. Molten magnesium is poured into a cast then solidifies into its mold… It can make reasonably intricate parts made cheaper than machine parts because it occurs abundantly in nature, in the form of a light malleable, ductile metal. In the body, magnesium is essential for many activities in the body including calcium utilization, cardiac function, energy production, many enzyme reactions, relaxation of muscles and restful sleep.

With a generation growing up in todays society physical tasks have almost become obsolete. Tasks such as even going shopping and going out to visit a friend can be done from the comfort of ...
In general, our bodies have been greatly depleted of magnesium for decades, and the foods we eat do not contain, as they did in the past, as much magnesium as may be needed. Fatty foods and alcohol actually inhibit magnesium absorption, and nearly forty percent of the magnesium in the foods we eat is lost during cooking. Consequently, many people have a greater need for magnesium supplements than for any other nutrient. In every muscle, calcium and magnesium have a reciprocal relationship. Calcium stimulates the muscles to contract while magnesium allows them to relax. When our bodies are deficient in calcium, we can borrow from the vast reserves in our bones.
But, when the body gets low in magnesium, we must obtain it from our muscles. As magnesium disappears from the muscles, calcium rushes in and the muscles tend to become tense or cramp. Many researches now believe that magnesium deficiency is also related to constriction and hardening of the arteries and high blood pressure. They have found that heart attack victims have low levels of magnesium in their blood and heart muscles. Magnesium is necessary for the metabolism of calcium, sodium, phosphorous, and potassium. Magnesium assists with the production of cellar energy, regulation of calcium, manufacturing of protein and normal muscle contractions.
Some people should take magnesium supplements on a daily basis. They can be especially beneficial during times of extreme stress or illness. Magnesium is also a treatment for insomnia, menstrual problems, PMS, and muscle cramps. It can be taken regularly, either in a pill form or an injection, to help prevent osteoporosis and cardiovascular disease. The human adult daily intake requirement for magnesium is about three grams. Check with your doctor to see what is right for you.
Asbestos is magnesium based fiber that was commonly used in a variety of insulating materials and as a fire-retardant. Most product have been banned by the U. S. government, and manufacturers have limited the use of this product.
Asbestos is a microscopic fiber that is found in either a bent or pin shape that is easily inhaled if broken apart. Today, it is found most commonly in older homes, in pipes, furnace insulation materials, shingles, millboard, textured paints, and floor tiles. When remodeling, improper attempts to remove these materials can release the fibers into the air, increasing the asbestos levels and endangering the people living in the home. Asbestos can cause lung cancer, mesothelioma (a cancer of the chest and the abdominal linings), and asbestosis (irrecoverable lung scarring that is fatal).

PHYSIOLOGY 525 SKELETAL MUSCLE JANUARY 28, 1998 There are three types of muscle: skeletal, smooth, and cardiac. From histology you know that skeletal and cardiac muscle are striated and smooth muscle is "smooth"- not striated. Muscles are often referred to as "sarco", from the Greek word meaning strength. Therefore instead of saying cytoplasm one uses sarcoplasm. The endoplasmic reticulum in ...
Symptoms of these diseases do not show up until many years after exposure began. Most people with asbestos-related diseases were exposed to elevated concentrations on the job; some developed diseases from exposure to clothing or equipment brought home from job sites.
Smokers are at higher risk of developing asbestos-induced lung cancer. Magnesium is also an important element in plant life. Chlorophyll is loosely based upon magnesium. The green color of vegetables and plants is due to chlorophyll, which is a molecule of magnesium.
Magnesium is also found in a variety of other foods. Many soy products such as tofu or soy flour also contain magnesium, as do many seeds and legumes. Most foods that are originally found beneath the soil are a reliable source of magnesium. Almonds, Brazilian nuts, pecans, and cashews contain some of the highest amounts of the element from edible nuts. Many types of fish contain the element too, specifically salmon. Also fruits such as dried apricots or avocados hold the element well.
Eating these foods proves to be beneficial to the body in the ways already stated and many more in the long run. As you can see, magnesium is a special element that is extremely useful in our lives. We come across every day, completely unaware that it is there or even what it is. Most elements are like that though, never thanked or recognized for the important roles they play in our world today. Life without elements wouldn’t be life at all. Without elements, such as magnesium, we would find ourselves without many of the conveniences and advancements in civilization that are currently available to us.
Society, as a whole, (not just chemistry students) should learn more about these elements and appreciate all that they have given them for without them, life wouldn’t be the same. With new advances in space exploration and more experimental research, we are sure to find many more elements which will make the life to come almost an effortless existance. 319.
