Research Paper On Chromium

chemical element here on our own planet Earth. Though it is a rare, unreactive noble gas,

Chroma was a young and beautiful goddess, who had the power of colors. She gave the gift of providing colours to mankind. By just one touch of hers would instantly give color. While one day when she was giving colors to flowers and she fell in love with a human man named Teo, who later she got married to. They had six kids in total, three of them were female while the other three were male, who’s colours were different two were brown, while the two were black and the two were white. Chroma and Teo loved each other so much that they could not live without each other.Teo’s brother Thase always got jealous of his brother Teo who was married to a beautiful goddess and had the perfect life. While one day when Chroma and her kids left to visit Olympus,

Chromium is not a new finding. Its original discovery was made during the 1700s when Johann Gottlob Lehmann acquired a mineral that had

Due to its stable half life, Nickel- 58 is proven to be natural. Moreover, due to it being a stable isotope, it will not go through radioactive decay. Nickel-58 can be found in the Earth’s crust (it makes up .01 -. 02 %), earth’s core and as well as meteorites where it is found coexisted with iron. Many experts believe the core is primarily made up of nickel and iron. It can also be created through fusion, the combining of of lighter atomic nuclei to form a heavy nucleus. The discovery of Nickel is a story of mistaken identity and superstition. During the 1600s, German miners were sent to find copper, but instead came upon a previously unknown nickel. Fast forward 100 years, in 1751, the Swedish alchemist, named Baron Axel Fredrik Cronstedt attempted to heat kupfernickel with charcoal and discovering its many properties, for instance it being white and magnetic, clearly revealing this was not copper. Cronstedt is credited as the first person to extract nickel and seperate it as a new

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.

Group 1- hydrogen: lightest element on the periodic table. lithium: lithium never occurs freely in nature. sodium:Sodium is the sixth most abundant element in the Earth's crust,. potassium:Potassium ions are necessary for the function of all living cells. rubidium: Rubidium has also been reported to ignite spontaneously in air. caesium:the element is only mildly toxic, it is a hazardous material as a metal and its radioisotopes present a high health risk if released into the environment. francium:Francium is the most unstable of the naturally occurring elements

Gallium is an element which was originally found in France. The city was not given to me so I am believing it was not recorded at the time. It was found by a scientist whose name was Paul Emile Lecoq. The year it was founded in was 1875. Its element symbol is Ga.

As seen on the right, Chromium is an element one may assume that it is nothing more than a disheveled piece of shiny silver. However, it is much more than that. Have you ever wondered how shiny car fenders are manufactured or perhaps what makes them so lustrous? To your surprise, or maybe not to your surprise, they are mostly made of the element Chromium! With that said, that is not the only purpose chromium serves.

In 1875, Paul-Emile Lecoq de Boisbaudran has discovered an element, Gallium. This element had been discovered in the country of France. Gallium is also known as “Ga” on the periodic table.

Associated with Hell and suffering, the word brimstone possesses an almost mythological nuance. In reality, brimstone is simply an element- specifically sulfur. When reduced to chemical makeup, brimstone loses its traditional implication surrounding eternal damnation. Sulfur exists in everyday objects, such as matches, and even in foods such as cruciferous vegetables and coconut products. However, this substance is still an integral ingredient to destructive forces such as fireworks and volcanoes. In order to understand this complex element, the chemical makeup and historical uses of sulfur must be analyzed. Then, the references in the Bible to brimstone may be understood deeper.

Iron is the fourth common element. It can be found in Earth's crust and core. There is an abundant amount of iron that can be found in the stars.

Selenium is a color of gray. Berzelius discovered selenium in 1817. Selenium is a chemical element with symbol Se and atomic number 34. The atomic mass of selenium is 78.96 the, melting point is 429.5 degrees F. In Fact, Some of the most important physical characteristics of selenium are its electrical properties. Also, Selenium is not produced in the body, but it is needed for proper thyroid and immune system function. Selenium is used to treat or prevent selenium deficiency and selenium is in some foods such as as whole grains, Brazil nuts, sunflower seeds, and seafood.Selenium is known as an essential element which means it is essential for life in some species, including humans. The most stable form,crystalline selenium, is metallic gray.

Elemental gallium is not found in nature. However, it is often found to be present in trace amounts in minerals such as diaspore, sphalerite, germanite, bauxite, and coal. Its main source of production is as a byproduct of zinc refining. It can also be obtained through electrolysis of a solution made of gallium hydroxide and potassium hydroxide. It has two stable

The primary compound steel contained chromium and was protected in 1865 by American metallurgist Julius Baur and produced by the Chrome Steel Co. of Brooklyn, N.Y. This amalgam steel was never fruitful, yet the reputation provoked an enthusiasm for chromium combination steels by French metallurgist Henri-Ami Brustlein. He soon discovered that to composite chromium with steel, the chromium mineral should have been refined to create an expert amalgam of iron-chromium-carbon. This expert amalgam would promptly break up into the melt of the pot process, generally the recuperation of chromium would be excessively whimsical, making it impossible to control the compound substance. Brustlein created and sold chromium amalgam steels for instruments, gun shells, and covering plate over a time of around 15 to 20 years before any other person entered the field. For his work in creating combination steel and related warmth medicines and applications, Brustlein should be known as the Father of Alloy Steels.

Due to the industrial restrictions in place across some the main areas of the world under health and safety regulations, finding an alternative plating process to the current hexavalent chromium process has become a real necessity. Trivalent chromium has proved to be a suitable replacement due to being less toxic, both health-wise and environmentally, whilst also demonstrating almost identical metal finishes to those of the hexavalent chromium deposits. However, the trivalent chromium chemical process is not without its difficulties, such as the inertness of the Cr3+ ions to be reduced to their metallic state, or the initial inferiority of the metal deposits physical properties in comparison to the deposits attained from conventional techniques. In order to overcome these issues multiple approaches have been investigated.
