Research Paper On Rhenium

The rare earth elements The United States currently only has one rare earth mine. And 98% exports comes from China which is currently taking advantage of their near monopoly by limiting the exportation. Scientists are engineering powerful rare earth magnets by combining iron, boron, and trying to reduce the neodymium, these rare earth magnets are not naturally found. And scientist all over the world have found creative and innovative uses for these magnets. For example a scientist has found that he can reduce the deaths of sharks by using magnets to repel the sharks by attaching it to fishing hooks. Though the hook was also attracted to the metal so he found the magnet with the least magnetic force, called samarium, that would also produce the same

In 1898, Marie and Pierre Curie announced they had discovered a new element that “behaved like pure barium” to the world. They named it radium for its radioactive properties. The Curies would have to prove their discovery with copious amounts of radium, and to do so needed to extract it on its own. They used the ore of pitchblende, which was high in supply in the Joachimsthal mine in Bohemia, to experiment with extracting the radium (Fröman, 2014). Marie used the process of boiling the pitchblende in acid used for cleaning and bleaching, which then left her with radium mixed with other metals. She then boiled what was left with a different solution and washed it, which cleared it of some of the metals (McClafferty, 2006). Marie boiled the remaining compound in another solution, washed it with water, and treated it with corrosive agents. These extensive processes allowed Marie to separate the metals from the radium sulfate and barium sulfate. To turn the sulfates into radium salt, she boiled them again.

Strontium is a chemical element with symbol Sr and atomic number (protons in nucleus) 38 and atomic weight 88.1 It is a soft, silver-gray metal, and has physical and chemical properties like to Calcium and Barium. It is available as four stable isotopes ubiquitously (Isotopes are differ in forms of an by number of protons in nucleus but possess a variable number of neutrons.) Strontium-88 is the most dominant among other forms, comprising 83% of natural strontium, where in additional three stable isotopes and their relative abundance are strontium-84 (0.6%), strontium-86 (9.9%), and strontium-87 (7.0%). Strontium is available ubiquitous vitally as as celestite (SrSO4) and strontianite (SrCO3), and it comprises about 0.025% of the earth’s crust. There are 16 major radioactive isotopes of strontium, but only strontium-90 has a half-life sufficiently long (29 years). In comparison with half-lives of remaining strontium radionuclides are fewer than 65 days. Strontium-90 decays to yttrium-90 by decaying a beta particle, and yttrium-90 decays by decaying a energetic beta particle with a half-life of 64 hours to zirconium-90. The key health concerns for strontium-90 are associated to the energetic beta particle from yttrium-90.2

The world was rocked in the aftermath of World War II. The destruction left in its wake would not only have us rebuilding and piecing together our governments, cities, and economies; but our humanity as well. A humanity that was shattered in the face of consequence and a confrontation of our darkest depths of humanity; the act of war. Word of human violation spread like wildfire post world war in occupation and battle hotspots. Happenings most inane, so inhumane, they were be hard to believe that they were true. Fortunately, the spread of globalization along with the after effects of war prompted nation leaders to convene and build together a framework, a concept of Human Rights. This very act prompted Non-Governmental Organizations that watchdog and protect the interest of our basic rights to arise. The weakest and most innocent among us requires the most protection. They are our legacy and they are our future. They are our children.

Artemis, goddess of fertility and twin sister of Apollo. It had the largest temple of ancient times. It was built of marble. It had 127 columns that fly 62 feet up to the tiled wooden roof. Carefully, cutted bases decorate 36 of these columns. The four bronze statues of Amazons were housed inside. The structure measured by 380 feet by 180 feet wide.

The construction of the Periodic Table of Elements was prior to the discovery of the individual elements. Elements such as silver, gold, tin, copper, lead and mercury have been known for centuries. In 1649, the first scientific discovery of an element was made by Hennig Brand when he discovered phosphorous. Prior to Brand’s discovery, chemists had acquired an immense body of understanding concerning the properties of elements and their compounds for the next 200 years.

To join a delightful touch of abnormality to your greenery separated territory this season, shouldn’t something be said in regards to making monster alliums? They’re an other get-together of ornamentals that appear to seem, by all accounts, to be straight out of a Dr. Seuss book! In addition, never get it from their looks, yet mammoth alliums are individuals from the onion family (sprouting onions).

Gallium is the element number 31. Gallium is the one of the only metal that will be liquid in your hand. Mercury is an liquid metal element number 80 that freezes at -280 degrees fairenheight with liquid nitrogen. Mercury was a popular thing to play with but people realized that they were slowly being poisoned by it.Gallium is not known to be toxic, but it can stain your hand dark brown. cesium is another metal that will literally melt in your hand but without putting it in an ampoule, it will explode and catch on fire. Gallium tends to be the less dangerous type of liquid metal other than explosive cesium to lethal mercury. Gallium melts at a temperatue of 83.4 fairenheight. In order to buy gallium you must first order it then, they must purize

56% of our population in The United States uses tap water on a daily basis. We shower in it, drink it, cook with it, and water out plants with it. How can we know that our water is safe? Well, yearly groundwater tests should be taken. Even if they are expensive; it is better to pay the small amount now, than having to pay millions of dollars for the health expenses of people later. There is a huge chance that chromium could be in our water; chromium is a chemical that is used extensively by different industries. For example, it is used to prevent corrosion in pipes (PG&E), leather tanning and electroplating. Electroplating is the process of changing the surface of a metal to prevent the surface from wearing out; this is widely used on cars,

In hardware it used to be used for the most part for electrical contacts however most now goes into chip resistors. In the substance business it is utilized as a part of the contacts for chlorine creation in electrochemical cells. Ruthenium is one of the rarest metals on the earth and is found as the free metal. Ruthenium is very contaminated and extremely hazardous to be around. Some of the compounds of ruthenium stain our skin and is reserved strongly in our bones. Ruthenium 106, one of its isotopes was used in testing the atmosphere of nuclear weapons, in the mid-1940s with a U.S. test and ended with a Chinese test. It’s one of those radionuclides that have and continue to produce improved cancer

There have been many elements that have been discovered in this world. The two latest elements that have been discovered are ununquadium and ununhexium. Ununquadium is element number 114 on the periodic table. It was given the official name of flerovium by the IUPAC in 2012. Ununhexium is element 116 on the periodic table. It was given the official name of livermorium by the IUPAC in 2012. There are two other elements that have been discovered, but not yet confirmed. Those elements are ununtrium and ununpentium. Ununtrium is element 113 on the periodic table and it has no official name yet. Ununpentium is element 115 on the periodic table and also has no official name yet.

Californium was discovered by bombarding curium with alpha particles. It is the heaviest element by weighable amounts. Very radioactive and harmful. One gram of californium cost 27 million dollars

It is not until recently that people have become dependent on this element, and not necessarily for the good of it, and the world. There is an obsession with uranium because of its unique properties. Uranium is extremely powerful because of its radioactive properties and unstable nuclei, especially that of Uranium-235. It is able to break down and release high frequency radiation through alpha and beta decay. It is because of these characteristics that Uranium has such a craze on the population of the world (Cox, 1995; Scerri, 2007). The properties of uranium allow people to create powerful plants to produce electricity, and weapons strong enough to destroy the world.

Ruthenium (Ru) is a transition metal element in-group 8, period 5, block d of the periodic table. It has an atomic number of 44 and is in a triad with Iron and Osmium. It was discovered independently in the residues left after crude platinum had been dissolved in aqua regina [1]. Ruthenium is one of the rare metals on earth and is generally found in the solid state [1]. It is generally found uncombined in nature although it is most commonly found associated with other platinum metals. It can also be obtained commercially from the waste created from nickel refining [2]. Since ruthenium is a rare transition metal it costs around 1.35 USD for a gram, which equates to approximately £0.95 per gram.

     In July of 1898, Marie and Pierre Cure discovered Polonium. They named the element after Marie's birth country, Poland. Chemically, this new element was very similar to bismuth, but it contained radioactivity, so it must be new. In December of 1898, the Curie's discovered yet another element. They named this one radium, from the Latin word for ray. The two new elements had completely different chemical properties, but they both had very strong radioactivity.
