Beryllium is a chemical element that has the symbol Be. It has the atomic number 4, the atomic weight of 9.012182, and the density of 1.85 grams per cubic centimeter. At room temperature its phase is a solid, and its element classification is metal. It is group number two, period number two, and its group name is alkaline earth metals. The name beryllium comes from the Greek word, beryl (The Element Beryllium). Beryllium is a scarce, but important element that has many uses in the world. Beryllium was first recognized by Abbe Hauy in 1798, who discovered a mineral with emeralds and beryl. Later that year, Louis-Nicholas Vauquelin discovered that an unknown element was present in emeralds and beryl (The Element Beryllium). However, beryllium was not isolated until 1828 by Friedrich Wolhler in Berlin and independently by Antoine Alexander Brutus Bussy in …show more content…
(Beryllium Element Information). It is also being used to make windows for X-ray tubes. When exposed to alpha particles, such as those released by radium or polonium, beryllium releases neutrons and is used as a neutron source. Beryllium is also used as a moderator in nuclear reactors (The Element Beryllium). The oxide has a very high melting point, which is why it is useful in nuclear work (Beryllium Element Information). Beryllium is found in about 30 different mineral species. The most important are beryl and bertrandite. Two precious forms of beryl are emerald and aquamarine. (Beryllium Element Information). Beryllium is available commercially, and would not normally be made in a lab. Its chemistry is dominated by its tendency to loose an electron to form BE2+ (Beryllium: The Essentials). The top three producers of beryllium in order are The United States, China, and Mozambique (Beryllium Element Information). Beryllium has 9 isotopes, but the only stable isotope is Be(Beryllium Element
Uranium was discovered in 1789, by Martin Heinrich Klaproth, a German chemist. He first believed the substance he got from pitchblende was pure uranium, but it was actually
Vanadium was first discovered by a Mexican chemist named Andres Manuel Del Rio. He sent a sample and a letter to The Institute of France in Paris, France. Unfortunately, the letter was lost in a ship wreck. So only the sample made it to the institute. Rio had first named this metal erythronium.
The Materion company was originally started with its predecessor called the Brush Beryllium Company. In the 1920’s, few outside of the scientific community knew about beryllium or its unique functions. But in 1921, Both Charles Bush Jr. and Dr. C Baldwin Sawyer saw its commercial potential and pioneered a way to remove the element from ore and create metals, oxides, and master alloys, and thus begun Brush Laboratories. The organization suffered a setback in 1927 with the death of 35-year-old Charles F. Brush, Jr. followed by the death two years later of Charles F. Brush, Sr. Associates Dr. Sawyer and Swedish chemical engineer Bengt Kjellgren, went on to create Brush Beryllium Company, the predecessor to Materion Corporation.
The first major producer was a Bohemian man named Joseph Riedel in 1835. He discovered that by using uranium salts as a colorant it would produce a bright yellow-green
In 1787, an unusual rock had come across the work of Dr. Adair Crawford when investigating witherite, a mineral in Strontian, Scotland ("Strontium | Periodic Table." Royal Society of Chemistry). The discoverer of the element was testing the results of witherite and hydrochloric acid. When Dr. Crawford mixed witherite with hydrochloric acid he did not get the results he expected. He assumed that his sample of witherite was contaminated with an unknown mineral, a mineral he named strontianite ("The Element Strontium." It's Elemental). The discovery by Dr. Adair Crawford was the start of strontianite, but it was not the end of research on this element. Although Dr. Crawford technically discovered strontianite, he did not prove that it was a new element. In 1791, Thomas Charles Hope, continued the investigation of strontianite ("Strontium | Periodic Table." Royal Society of Chemistry). Through his investigation, Hope proved that strontianite was a new element. Finally the element, now known as Strontium, was isolated. Strontium was first isolated by Sir Humphry Davy, an English chemist, in 1808 through the electrolysis of a mixture of strontium chloride and mercuric oxide ("The Element Strontium." It's
Thrane Esmark and identified by a Swedish chemist, Jӧns Jacob Berzelius in 1828. Thorium was
The element I got was Lead, Lead is a chemical element that is assigned the symbol Pb it is from the Latin plumbum and it is a bluish-white element, Lead is not really rare but since it is fairly widespread and easy to extract it typically occurs in very small amounts in ores and is found in the ores galena, anglesite, cerussite and minim also the earth’s crust contains approximately 0.0013 percent lead. Lead can be toxic to humans and animal but is found mostly in combination and used a lot in cable sheaths, batteries, solder, and pipes, its ductility and resistance to corrosion with tiny leaks, make it a particularly good material for constructing water pipes. This element has been known since ancient years and the year is unknown when it
Those different forms of the element are called isotopes. Each isotope has a half-life, for example if I bought 10 grams of an isotope whose half-life is 437 years. After the 437 years I would only have half the amount of what I bought. Americium has 12 isotopes which known are known to not be natural and are known to have a mass number between 232 and 247. The longest-lived isotopes of Americium are Americium 243 at a half-life of 7370 years, Americium 241 at a half-life of 432.2 years, and Americium 242 at a half-life 141 years. Even though Americium 243 and 241 are the most abundant of Americium’s isotopes, Americium 241 is the most
First discovered by English scientist Sir Humphrey Davy in 1808 , boron was popular ever since. Boron has been used for thousands of years , but this element had not been purely isolated until Sir Humphrey Davey isolated it. Boron had not been successfully isolated until this date because boron does not naturally occur in its elemental form. Davy did isolate this material by using voltaic piles and electrolysis to separate boron. Today boon is used commonly. Its applications range from pyrotechnics to rocket fuel.
Balard found bromine chemicals in the ash of seaweed. The seaweed was used to produce iodine, but also contained bromine. Balard distilled the bromine from a solution of seaweed ash saturated with chlorine. The properties of the left over substance resembled that of an intermediate of chlorine and iodine, he was sure that he had found a new element and named it muride, derived from the Latin word muria for brine.
Molybdenum is used as glass furnace electrodes due to its high melting point. It is also used in the petroleum industry, to catalyze the removal of organic sulfur compounds in coal liquification and gas liquification processes. Molybdenum is an essential trace element for animals and plants. molybdenum can cause diarrhea, growth retardation, infertility, low birth weight, and gout; it can also affect the lungs, kidneys, and liver.
According to Google and other web sites around 1807 in England, Kalium, also known as potassium was discovered by Humphrey Davy. Mr. Davy discovered potassium by excluding water from
Helium is the second most abundant element in the universe, but there is a shortage on earth.In one of the main helium reservoirs in the U.S. there was only 10 - 12 billion cubic feet of helium left in it, as of 2012. Even though this seems like a lot, we use around 2 billion cubic feet of helium per year. So technically that reservoir would be getting very very close to
Pierre Janssen discovered helium in the spectrum of the corona of the sun during an eclipse in 1868. Shortly after it was identified as an element and named by the chemist Sir Edward Frankland and the British astronomer Sir Joseph Norman Lockyer. The gas was first isolated from terrestrial sources in 1895 by the British chemist Sir William Ramsay, who discovered it in cleveite. In 1907 Sir Ernest Rutherford showed that alpha particles are the nuclei of helium atoms.
While its atomic number is four, its atomic mass is nine. Beryllium is in the second group with other metals like Magnesium, Calcium, Strontium, Barium, and Radium. In the second period with Beryllium are Lithium, Boron, Carbon, Nitrogen, Oxygen, Fluorine, and Neon. Everyone in the group all are Alkaline Earth Metals with the same phase. Beryllium is one of the three elements in the second row that is a solid element.
