Nature of Chemistry and Physics of Beryllium
Beryllium (beryllium) is a toxic, gray, strong, lightweight bivalent element, and is primarily used as a hardening agent in metal alloys.
Beryllium is one of the lightest metals with the highest melting. These metals have excellent thermal conductivity, not magnetic, resistant to concentrated nitric acid, as well as at standard temperatures and pressures capable of resisting oxidation when exposed to air.
The crust has a beryllium content of 2.6 ppm and 6 ppm in the soil. Beryllium in soil can enter into plants that grow on it.
Beryllium levels vary between 1 and 40 ppb, too low to affect the animals that eat the plants.
Beryllium is found in 30 different minerals, the most important being bertrandite, beryl, chrysoberyl, and phenacite.
The precious beryl forms (precious stones) are aquamarine and emeralds.
Use of Beryllium
Beryllium is used as an alloying agent in the production of beryllium-copper.
Beryllium-copper is used in a variety of applications due to its excellent electrical and thermal conductivity, high strength and hardness, non-magnetic properties, as well as good resilience.
Typical applications of beryllium-copper alloys are in the defense and aerospace industry.
Beryllium is also used in X-ray diagnostic detection because it is transparent to X-rays and in the manufacture of various computer equipment.
Beryllium Health Effects
Beryllium is not an essential ingredient for the human body, it is even one of the most toxic chemicals.
This metal can be very dangerous when inhaled as it can damage the lungs and cause pneumonia.
The most common effect of beryllium is called berylliosis, a dangerous lung disorder that can also damage other organs, such as the liver.
About 20% of all cases of berylliosis cause death. Inhalation of beryllium in the workplace is a major cause of berylliosis.
Beryllium can also trigger allergic reactions in people who are very sensitive to these chemicals.
Allergic reactions can be very severe. This condition is also known as Chronic Beryllium Disease (CBD).
Symptoms of CBD include weakness, fatigue, and breathing problems. Some people who suffer from CBD will develop anorexia and bluish on the hands and feet.
In addition to causing berylliosis and CBD, beryllium can also increase the risk of cancer and DNA damage.
Environmental Impact of Beryllium
Beryllium enters the air, water, and soil resulting from natural processes and human activities.
Beryllium occurs naturally in small amounts. Humans added the concentration of beryllium through the production of metals and the burning of coal and petroleum.
Beryllium will not accumulate in the fish body. However, some types of fruits and vegetables such as red beans and pears may accumulate beryllium in significant levels.
Animals that eat the plants will experience an increase in beryllium as well. But fortunately, most animals immediately release beryllium through urine and feces.

Atomic number: 12
Atomic weight: 24,305
Classification: alkaline metals
Phase on TemperatureRoom: Solid
Density: 1.738 grams per piece diced
Melting point: 650 ° C, 1202 ° F
Boiling Point: 1091 ° C, 1994 ° F

Under standard conditions magnesium is a light metal with a silvery white color. When exposed to air, magnesium will fade and become protected by a thin layer of oxide.
When magnesium comes into contact with water, magnesium will react and produce hydrogen gas. If submerged in water, you will see a gas bubble begin to form.
When burned, Magnesium is very bright white. At one time magnesium powder was used to produce flashes of light for photography.
Where is magnesium found on Earth?
Magnesium is quite abundant on Earth in compounds and is found in over 60 different minerals in the Earth's crust. Some of the most important minerals include dolomite, magnesite, talc, and carnalite. The magnesium oxide (MgO) compound is the second most massive compound in the earth's crust of about 35% of the heavy crust.
Significant amounts of magnesium are also found dissolved in seawater. In the sea water it takes the form of the Mg2 + cation. Much of the commercial magnesium used in the United States comes from the electrolysis process using extracts from seawater.
How is magnesium used today?
One of the major uses of magnesium metal in metal alloys. Because it is both strong and light. It is often mixed with aluminum, zinc, manganese, silicon, and copper to make a strong and light alloy for use as automobile parts, aircraft components, and missiles.
Magnesium metal is also used in electronic components. Good light and electrical properties make good elements for use in cameras, mobile phones, laptop computers, and other handheld electronic components.
Other applications of magnesium in various compounds. Some compounds are used as medicines such as magnesium hydroxide used to help digestion (Milk of Magnesia) and magnesium sulfate (Epsom salts) used in bath soap to relieve sore muscles.
The human body needs magnesium for health. It is used to make proteins, strong bones, and to regulate body temperature.
How is magnesium found?
The first Scottish chemist Joseph Black pointed out in 1755 that the substance of alba magnesia is a distinct elemental compound, one of which is magnesium. The element was first isolated by the English chemist Sir Humphry Davy in 1808.
Where does the name magnesium come from?
Magnesium gets its name from the Magnesia district of Greece where magnesium carbonate compounds were first discovered.
Isotope
Magnesium has three stable isotopes including magnesium-24, magnesium-25, and magnesium-26.
Interesting Facts about Magnesium
For many years magnesium is considered the same element as calcium.Api magnesium is very difficult to extinguish because it can burn in nitrogen, carbon dioxide, and water.Magnesium is used in flares and fireworks because bright white light when burned.If we splash water over Magnesium fire, it will only make the fire bigger. Magnesium is sometimes used to help relieve migraine headaches

Hi, laras
BalasHapusI want to ask you, What is thermal conductivity?
Thermal conduction is a transport phenomenon in different temperatures causing the transfer of energy from a single hot object to the same region at a lower temperature. Heat transferred from one point to another through one of three methods of conduction, convection, and radiation.
HapusCan you explain to me the difference of fluorine and chlorine?
BalasHapusFluor is a chemical element in the periodic table that has the symbol F and atomic number 9. Its name is derived from Latinfluere language, meaning "flow". It is the most chemically and electronegatively reactive yellow-green toxic halogen gas of all the elements. In its pure form, it is very dangerous, can cause severe chemical combustion so related to the skin.
HapusHi laras, i want to ask. Whether beryllium and magnesium can bind?
BalasHapusBeryllium (Be), Magnesium (Mg), Calcium (Ca), Strontium (Sr), Barium (Ba), and Radium (Ra). It is called metal because it has properties like metal. It is called alkali because it has alkaline or alkaline properties when reacted with water. And the term soil because of its oxidation is difficult to dissolve in water, and is found in many rocks in the earth's crust.
HapusEach metal has the same electron configuration as the noble gas or class VIII A, after which 2 electrons are added to the outermost layer of S skin. For example electron configuration on Magnesium (Mg) is: 1s22s22p63s2 or (Ne) 3s2. The bonds that most of the alkaline earth metal compounds have are ionic bonds. Because, the outer electron is ready to be released, in order to achieve stability.
