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". Nickel was discovered by Axel Fredrik Cronstedt, in Sweden, during the year 1751. Mr. Cronstedt discovered nickel in a mineral called niccolite. He originally planned to extract copper from...
hydrochloric and sulfuric acid. It also decomposes readily in nitric acid.

As one can see, the element Nickel is a very useful element in our society. It is used in many ways commercially, while presenting very little biohazards, among other dangers such as pollution. Though not being present all over the earth, it is used all over the world in many different ways. Its uses are very plentiful, ranging from the production of green-tinted glass to being used as a protective coating for other metals. Nickel is definitely one of the more useful, profitable elements on the periodic table.
Niels Bohr"s model of the hydrogen atom, was the primary reason for the understanding of energy levels.Bohr was able to explain the bright line spectrum of hydrogen. Sparked by the recent discovery of the diffraction patterns, scientists believed electrons could be described as waves. Bohr hypothesized that energy is being...

Introduction Sulphate ions and iodine can be formed from reactions between peroxodisulphate ions and iodine ions. S2O82-aq + 2I-aq -----------> 2S042-aq + I2aq The reactants and the sulphate ions are colourless so the achievements of the experiment must be determined by the iodine produced. If...

One clear representation, which will be discussed later, of the controversy surrounding the use of synthetic products versus natural products, lies in vitamins. A vitamin is a composite of the natural world that is made up of enzymes, coenzymes, antioxidants, and mineral activators. The decision on which one a person...

OXYGEN O Oxygen was discovered by a British chemist, Joseph Priestly in 1774, and independantly by Carl Wilhelm Scheele, a Sweedish chemist. Oxygen has many uses - it is used in welding torches, to assist in hospital patient"s breathing and in metal fabrication industries. Oxygen is also used for defense...

Background An example of a gas would be hydrogen. A chemical property is how a substance changes its identity. An example of this would be being able to support flammability. A physical property distinguises one type of matter from another and can be observed without changing its identity. An example...
