All You Want to Know on Flerovium

The elements were organized by Dimitri Mendeleév. He organized them by properties (columns), groups (horizontal), and atomic number (the number of protons and electrons). This became known as the Periodic Table. And currently there are 118 elements. He also found gaps in which elements that were yet to be discovered were to go, three of these unknown elements were found and identified in Mendeleév's lifetime. The elements today are used in everything and 75% of the 118 elements are metal.

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

The existence of Gallium was proposed in 1871 by Russian chemist Dmitri Mendeleev, who named it, based on its position in the periodic table, “eka-aluminum”. He also predicted it’s melting point, density, oxide character and bonding in chloride, that were all similar to the real properties of Gallium.

Fluorine is an element that reacts with minerals in the earth to create a salt. The salt is often naturally occurring in nature and is found in very small amounts in urban and rural wells. Although it is

A review of the records reveals the member to be an adult female with a birth date of 12/07/1969. The member has a diagnosis of osteoarthritis. The member’s treating provider, Peter Townsend, MD recommended the member use the Flector 1.3% patch.

Krypton, (symbol being Kr), is a very interesting element. It was discovered May 30, 1898 by Sir William Ramsay and Morris M. Travers, who were Scottish and English chemists. Krypton was named from the Greek word ‘kryptos’, which means hidden. It was found when the chemists were studying liquefied air. It is about 0.0001% of the earth atmosphere. It can also be found in some photographic flashes, some fluorescent light bulbs, and can be combined with other gases to make signs with a greenish-yellow glow.

In final analysis, the electronegativity and density periodic trends trends are fairly consistent. Electronegativity decreases when going down groups, while density increases. However, the outliers of these trends are the noble gases, because of their stable, unreactive properties. In addition to helping students learn about periodic trends, it also demonstrated to students how these trends were of great use for previous scientists when they worked together to discover new elements that were missing on the periodic

Fluorine (F) is an element found in the 7th group of the periodic table from the halogen family. It’s an element that most reactive as it only needs to gain one electron to form Fluoride ion (F-). It’s in this form of fluoride that is found in our drinking water also known as fluoridated water. Water, food and living organisms are exposed to inorganic fluorides and they are hydrogen fluoride (HF), calcium fluoride (CaF2), sodium fluoride (NaF), sulfur hexafluoride (SF6) and silicofluoride. Fluoride compounds are plentiful in the earth’s crust and naturally found in rocks, soils, salt and sea water, representing approximately 0.06-0.09%.

The book “The Periodic Table” by Primo Levi is undoubtedly a masterpiece. It showcases the enthusiasm, the level of dedication, and passion successful chemists such as Primo Levi himself had for the field of their expertise. The way Primo Levi has related the troublesome times and events he had to face in prospect with the elements of the periodic table is laudable. Primo Levi is surely an inspiration and a perfect example of prodigy and passion. Despite the challenges and the hardships inflicted on him by the bigoted group of Germens, he still managed to emerge as an exceptional chemist and an author who made great contributions to the modern chemistry as we now know it.

The German alchemist, Albertus Magnus from the 13th century, is the man who is known for first identifying Arsenic. Being number 33 on the periodic table, arsenic falls inside the metalloid line because of its characteristics. According to the Green Facts website “Arsenic is a naturally occurring element that can be found in the Earth crust.” (Arsenic n.d.) It

Benign prostatic hyperplasia (BPH) or commonly referred as enlarged prostate, occurs in more than 50% of men in their sixties and up to 90% in their seventies and eighties. The condition’s hallmark symptoms include frequency, hesitancy, urgency, post void fullness and nocturia. These symptoms can greatly affect quality of life of men who suffer from them. Flomax is one of the medications that help to relieve symptoms of BPH. The drug was developed by Boehringer Ingelheim pharmaceutical company and approved by the Food and Drug Administration (FDA) in 1997. The purpose of this paper is to provide an in-depth discussion of Flomax based heavily on the 21-page long information provided by the pharmaceutical company.

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.

Florbetapir is a radiopharmaceutical used in the diagnosis of AD. In vitro studies have shown that florbetapir binds selectively and saturably to β-amyloid plaques in brain tissues via the β-amyloid ligand. Once bound florbetapir allows for the density of the plaques to be measured. Florbetapir half life (T1/2 = 109.75) is significantly longer than that of C-PIB thus leading to a longer duration of action in the brain and increased accumulation in β-amyloid plaques. Ninety minutes after administration the radioactivity remaining in the blood (approximately 2% ID) is predominantly polar metabolites.7 Florbetapir is rapidly cleared from the blood stream after IV injection, less than five percent of the radioactivity can be measured after 20 minutes. 8 Florbetapir has been well tolerated in clinical trials with the common side effect being headache. Florbetapir is synthesized by the nucleophilic displacement of a tosylate group in the precursor molecule by radioactive fluoride. This is then followed by the removal of tert-butoxycarbonyl protecting group via the use of acid.7 The radioactive fluoride is originally isolated by the utilization of ion exchange chromatography.7

Dimitri Mendeleev was considered the first chemist to discover that patterns would become apparent when elements were classified to their properties. Mendeleev’s adjustment of elements was the one and only due to his idea of leaving blank spaces for elements he believed were undiscovered in 1869. The purpose of the Mendeleev Lab of 1869 is to use knowledge of the periodic table in order to identify the undiscovered elements. Ultimately the whole idea is to observe, and draw conclusions to identify the elements. For instance, observing properties, samples, and trends will help us learn more about the periodic table also, learn more about the hidden elements of Mendeleev’s Lab.

     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.
