Chemical Element and Nickel

Nickel is one of the most important elements on the periodic table. It has plenty of history, as well as a huge importance to society. Its has unique chemical, physical, and geological properties. Nickel is used commercially in abundance, as it is used anywhere from simple art products such as ceramics to complex structures such as tubing for desalination plants. It is even used in the American five-cent coin, the "nickel".<br><br>Nickel was discovered by Axel Fredrik Cronstedt, in Sweden, during...

Chemical Element and Titanium

and 26 Neutrons. Titanium has a high resistance to high temperatures, it’s boiling point is at 3287°C and its melting point at 1668°C. Pure titanium is a lustrous white metal. Titanium is able to burn in air and it is the only element that will burn in Nitrogen. The element will combine with chlorine at 550°C, and at red heat temperatures it is able to combine with oxygen. When dissolved in iron, tin or zinc, the metal turns purple, and when dissolved in sulfuric acid, it turns yellow. This...

almost immune to chemical attack at temperatures below 150 C. Tantalum is virtually resistant to corrosion due to an oxide film on its surface. Applications Tantalum finds use in four areas: high-temperature applications, such as aircraft engines; electrical devices, such as capacitors; sirurgical impants and handling corrosive chemicals. It is rarely used as an alloying agent because it tends to make metals brittle. Tantalum resist corrosion and is almost impervious to chemical attack, for this...

Chemical Periodicity

Chemical Periodicity Engr. Imelda Galera De La Salle University-Dasmariñas Dasmariñas, Cavite Philippines ABSTRACT Chemical periodicity was demonstrated using different samples of elements from Group IA, IIA and IVA. These samples are: Li2CO3, Na2CO3, K2CO3, MgCO3, CaCO3, BaCO3, Carbon, Tin, Silicon and Lead. Each sample was placed in a test tube, (one sample and one test tube) and the physical color, appearance and state was defined. Water was used to test the solubility of the element...

Atoms, Molecules, and Elements - Paper

Molecules, and Elements Sarah Dowling CHM/110 July 30, 2012 Elizabeth Frayne, PhD. Atoms, Molecules, and Elements Dmitri Ivanovich Mendeleev (1834-1907) was a Russian chemist famous for his formulation of classification of elements, or what is now called the Periodic Table of Elements (2011). On 6 March 1869, Mendeleev made a formal presentation to the Russian Chemical Society, titled “The Dependence between the Properties of the Atomic Weights of the Elements”, which described elements according...

Scanduim Element

Scandium is a chemical element with symbol Sc and atomic number 21. A silvery-white metallic transition metal, it has historically been sometimes classified as a rare earth element, together with yttrium and the lanthanoids. It was discovered in 1879 by spectral analysis of the minerals euxenite and gadolinite from Scandinavia. Scandium is present in most of the deposits of rare earth and uranium compounds, but it is extracted from these ores in only a few mines worldwide. Because of the low availability...

Chemical Periodicity

Chemical Periodicity ------------------------------------------------- ABSTRACT The experiment chemical periodicity shows the properties and reactions belonging to group IA, IIA, and IVA. Proper procedures and observations were done to determine the solubility, physical state, color, and appearance of the compounds namely Li2CO3, Na2CO3, K2CO3, CaCO3, and BaCO3. The results shows that Li2CO3, Na2CO3, K2CO3 were soluble in water, while MgCO3, CaCO3,and BaCO3 were not soluble. All of these compounds...
