What is nickel?
is a metal chemical element, classified between transition metals on the periodic table of elements. People have been using this metal in alloys for thousands of years, as its traces in ancient sculptures and weapons suggest, even though they may not know about the exact characteristics of the element. There are a number of commercial nickel applications, making it a very valuable and useful metal; Several corporations specialize in the extraction and processing of ore, along with other metal elements. The metal is also ferromagnetic and very towing, which means that it can be easily melted and processed. It is relatively hard and strong, making it a great accessory alloy with softer or fragile metals. In the periodic table of elements, it is identified with the Ni symbol and has atomic number 28. This is a reference to the fact that Ruda can resemble copper red, which leads some people to compare ore with work or devil fraud. This ore was used in glaze for ceramics thanIts properties were fully understood because it created a distinctive green blue color. The element was first isolated in 1751 Alex Fredrik Cresthedt, who actually tried to get copper, but instead ended nickel.
Because nickel resists corrosion and is relatively strong, many people use it in alloys; For example, stainless steel often contains this metal. It is also used for other metal plates to ensure that they are protected from corrosion. The metal is also traditionally used to replace silver in coins; For example, the American coin of nickel once contained a lot of metal, although it is no longer. Sometimes it is mixed in Glass when a distinctive green color is required.
Although nickel is not generally toxic, the element bears some warnings. Many people experience contact dermatitis when they are exposed to this metal, making it a bad choice for jewelry alloys. Vapors and dust can also be a velMi harmful, causing pulmonary infections and irritation. People who work with metal, especially nickel sulfide, should always wear the right face and mouth protection to remain healthy. The gases that contain nickels are also very toxic and need to be avoided.
