Chlorine
Chlorine Chlorine Chlorine is (at room temperature) a greenish-yellow gas that can be readily liquefied at 5170 Tarr or 6.8 atmospheres, at 20 C (68 F), and has a very disagreeable odor. It’s Element Symbol is Cl, atomic number is 17, and atomic mass is 35.453. Chlorine’s melting point is -101 C or 149.8 F. The boiling point is -34.05 C or -29.29 F, at one atmosphere pressure. Chlorine is a member of the halogen group. Chlorine was discovered by Swedish scientist Karl Wilhelm in 1784, but he fi

Oxygen
Oxygen Oxygen Oxygen, symbol O, colorless, odorless, tasteless, slightly magnetic gaseous element. On earth, oxygen is more abundant than any other element. Oxygen was discovered in 1774 by the British chemist Joseph Priestley and, independently, by the Swedish chemist Carl Wilhelm Scheele; it was shown to be an elemental gas by the French chemist Antoine Laurent Lavoisier in his classic experiments on combustion. Large amounts of oxygen are used in high-temperature welding torches, in which a

Oxygen Oxygen Oxygen and its compounds play a key role in many of the important processes of life and industry. Oxygen in the biosphere is essential in the processes of respiration and metabolism, the means by which animals derive the energy needed to sustain life. Furthermore, oxygen is the most abundant element at the surface of the Earth. In combined form it is found in ores, earths, rocks, and gemstones, as well as in all living organisms. Oxygen is a gaseous chemical element in Group VA of
The Element: Chlorine
The Element: Chlorine
The Element: Chlorine The Element: Chlorine General Information We researched the chemical element known as chlorine. Chlorine has an atomic number of 17 and an atomic weight of 35.453. It has a valence number of 3. The element has 3 energy levels. Chlorine exists as a greenish-yellow gas at normal temperatures and pressures. Chlorine is second in reactivity only to fluorine among the halogen elements. Chlorine is a nonmetal. It is estimated that 0.045% of the earth\'s crust and 1.9% of sea wate
Lithium
Lithium
Lithium Word Count: 1103 In 1817, an aging Swedish chemist was pouring over his work on a late afternoon in Stockholm, Sweden. He was analyzing a strange ore named Petalite that had been procured from an island off the coast of Sweden called Utö. The ore Petalite (which is now recognized to be LiAl(Si2O5)2) had been discovered by a Brazilian scientist, José Bonifácio de Andrada e Silva towards the end of the 18th century on a visit to Sweden. This Swedish scientist, Johann August Arfvedson, det
Magnesium
Magnesium
Magnesium Word Count: 1305 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 sh

Potassium
Potassium Word Count: 670 Potassium Potassium is a vital element in the human body. Potassium had never been distinguished between sodium until the eighteenth century. Before potassium was recognized as an element, potassium carbonate was mixed with animal fat to make soap. It was discovered by Sir Humphrey Davy in England, in 1807. Sir Davy was able to isolate potassium using electrolysis. Potassium was the first metal isolated by this procedure. Today, it is still not found free in nature. It
Sodium
Sodium
Sodium Word Count: 376 Life could not exist without compounds of sodium. These compounds hold water in body tissues, and a severe deficiency of sodium can cause death. Blood contains sodium compounds in solution. Sodium compounds are used in industry in the manufacture of chemicals and pharmaceuticals, in metallurgy, in sodium vapor lamps, and in the production of hundreds of every day products. One of the most common sodium compounds is table salt, or sodium chloride. In its pure form sodium i
The Discovery Of Fluorine
The Discovery Of Fluorine
The Discovery Of Fluorine Word Count: 333 The isolation of fluorine had challenged chemist for many years, taking the lives of at least two scientists in the process. Fluorine receives its name from the Latin, fluo, meaning flow. The first real attempt to free fluorine, was done by a chemist by the name of Humphyry Davy, between the years of (1811-1813). He first tried to liberate the element by using the chemical methods, but this failed. He then went on to try and electrolysis process using b
