Americium: Element 95 On The Periodic Table

In summarization,osmium ,Os, is a chemical element based on the periodic table. This element was discovered in the mixture of a mixture of nitric and hydrochloric acids. It has a atomic number of 76 and an atomic mass of 190.23. This is the most rarest of 118 chemical elements. Though this element is overlooked, this element has great

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 name of my element is carbon. Its symbol is the letter “C” and its atomic number is 6. Its atomic mass is 12.0107. Carbon’s abundance on the earth’s crust is 200 parts per million by weight and 344 parts per million by moles. You can buy 100g of carbon for $2.40.

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.

Scientists at the Join Institute of Nuclear Research in Dubna, Russia and scientists at the Lawrence Livermore National Laboratory in California discovered element 117 or, tennessine, in 2010. With an atomic mass/weight of 294 making it the second heaviest element known to mankind behind element 118 or, Oganesson. Before being named tennessine by the International Union of Pure and Applied Chemistry (IUPAC) in 2016, tennessine had the place holder name of ununseptium, which means one-one-seven in Latin. Tennessine was created by fusing berkelium-249 atoms with calcium ions until tennessine atoms formed. Since tennessine is radioactive, it has zero stable isotopes. Tennessine’s most stable isotope, however, is tennessine, which has a half-life of about 80 milliseconds. Only six atoms of tennessine have been artificially created to this day.

I once owned a very strange cat named Francium. Why was he called Francium you ask? He had many similar properties of the element Francium.

Arsenic has an atomic number of 33 and a relative atomic mass of 74.922amu. Arsenic is an odd element, as it acts like metal even though it is a natural element. Arsenic is found in natural environments, and in limited quantities found in rocks, soil, water and more. Arsenic was very known to the ancient Egyptians and the Chinese, they used Arsenic as a way of gilding metals. The orpiment(As2S3) and the realgar (As4S4) : are the two Arsenic sulphide minerals that Greek Philosopher, Theophrastus. As2O3 is the trioxide, is one of the end products of copper refining. This is a form of arsenic that has also been known for awhile now, and it is called white arsenic. The official discovery of arsenic is to Alberts Magnus in around the 1200s. As to the physical property, it is radiant, has a silver colour and fragile, as it is a semi-metal. When in exposed to air, it is rapidly damaged, because of the usual elements in air, such as nitrogen and more. Arsenic is not particularly used in any technology, but recently we use Arsenic in semiconductor gallium arsenide, it can convert electric currents to laser lights. Usually it is not used

On November 9th, 1994, there was a chemical element called Darmstadtium. It’s a radioactive heavy metal that is name after the city Darmstadt, Germany where it was first found. It’s a manmade element that Yuri Oganessian Vladimir Utyonkov at the JINR made isotope 273 by combining plutonium and sulfur together. Within the same year, Peter Armbruster and Gottfried Munzenberg from the GSI unit uses lead and nickel to combine it with isotope 269 into the previous isotope. With the combinations it created a new element and called it element 110. There is still little known things about the element such as the boiling point and the melting point.

The most popular type of smoke alarm is an ionization chamber smoke alarm. These contain 0.28 micrograms of the radioactive isotope americium 241, in the form of americium dioxide. Americium is a synthetic element, so it must be produced in a nuclear reactor. Americium is made from plutonium 241, yet this needs to also be made in a nuclear reactor. Uranium 238 in a nuclear reactor it is hit with a neutron, which makes uranium 239. Uranium 239 has a half-life of 23.5 minutes, the uranium goes through beta decay becomes neptunium 239. This neptunium will then form plutonium 239 via beta decay over two days, this is then bombarded with two neutrons to become plutonium 241. Plutonium 241 has a half-life of

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.

There are theories in the world that claim everything is connected. Many people often back up this theory as being true, " All is connected... No one thing can change by itself." Some how everything has an effect on something else or is related to something else. Even five completely different things can be related. Things such as Amethyst, Himalayan Salt lamps, Tijuana, Jennifer Aniston, and Peace can all be related in some way. A theory on how they are all somehow related should be easy to do with the right research.

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.

Potassium is a very important element in the Periodic Table of elements. Potassium is used for a multitude of things and is crucial to the human body. Potassium is made in the oxygen burning shell of stars when they explode. Potassium is also a necessity to plants. Humans and all other forms of life need minerals from Potassium to survive.

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

Henry Gwyn Jeffreys Moseley used X-ray crystallography and made it possible to assign atomic numbers to the elements. X-ray crystallography is a tool used for identifying the atomic and molecular structure of a crystal, in which the atoms cause a beam of X-rays to reflect into many different directions. Moseley found that the exact number of lanthanides had to be 15 and that element 61 still wasn't
