Nickel Metal - The Facts Nickel Metal - The Facts. Nickel is a naturally occurring, lustrous, silvery-white metallic element. It is the fifth most common element on earth and occurs extensively in the earth's crust. However, most of the nickel is inaccessible in the core of the earth.

Nickel Nickel (atomic number 28) resembles iron (atomic number 26) in strength and toughness but is more like copper (atomic number 29) in resistance to oxidation and corrosion, a combination accounting for many of its applications. Nickel has high electrical and thermal conductivity.

- Nickel(II) chloride (or just nickel chloride), is the chemical compound NiCl 2. The anhydrous salt is yellow, but the more familiar hydrate NiCl 2 ·6H 2 O is green. Nickel(II) chloride, in various forms, is the most important source of nickel for chemical synthesis. The nickel chlorides are deliquescent, absorbing moisture from the air to form a solution.

Nickel CAS ID #: 7440-02-0. Summary: Nickel is a very abundant natural element. Pure nickel is a hard, silvery-white metal. Nickel can be combined with other metals, such as iron, copper, chromium, and zinc, to form alloys. These alloys are used to make coins, jewelry, and items such as valves and heat exchangers.

Nickel Nickel is a white metal, with a faint tinge of yellow. It is used widely in making alloys, including copper-nickel (75% copper, 25% nickel) which is used in coinage. Nickel is used in the production of the strongly ferromagnetic alloy alnico which is used to make strong permanent magnets. Alnico alloys iron, nickel, cobalt and aluminum. Stainless steel contains 12-18% chromium and usually about 8% nickel. Iron objects can be plated with nickel for corrosion resistance.

Nickel Nickel-plated objects sometimes provoke nickel allergy. Nickel has been widely used in coins, though its rising price has led to some replacement with cheaper metals in recent years. Nickel is one of four elements (the others are iron, cobalt, and gadolinium) that are ferromagnetic at approximately room temperature.

- Top Definition. nickel and dime. Traditionally used as part of the larger phrase To be nickled and dimed to death, referring to the undesired price of upkeep for a certain item. More fundamentally, it refers simply to seemingly hidden ongoing expenses which, over time, add up to a large expense.. nickel and dime. From the construction subculture, a verb meaning the act of bargaining down a price for something way below reasonable rates.. that contractor nickle and dimed my wages down to rates that were low for 5 years ago.

Nickel Nickel is a chemical element with symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel belongs to the transition metals and is hard and ductile. Pure nickel, powdered to maximize the reactive surface area, shows a significant chemical activity, but larger pieces are slow to react with air under standard conditions because an oxide layer forms on the surface and prevents further corrosion. Even so, pure native nickel is found in Earth's crust onl

- Kupfer means copper and the term nickel in German referred to Satan or the devil. Discovery: Baron Axel Fredrik Cronstedt discovered nickel in 1751 in kupfernickel (niccolite). Properties of nickel. Nickel is a hard, malleable, ductile metal with ferromagnetic properties. It is silvery white and can conduct heat as well as electricity. The sulfates and oxides of metal are commonly used in many products.

Nickel (United States coin) A nickel, in American usage, is a five-cent coin struck by the United States Mint. Composed of 75% copper and 25% nickel, the piece has been issued since 1866. Its diameter is.835 inches and its thickness is.077 inches. Due to inflation, the purchasing power of the nickel continues to drop and currently the coin represents less than 1% of the federal hourly minimum wage. In 2015, over 1.5 billion nickels were produced at the Philadelphia and Denver mints. The silver half dime, equal to five cent

- Because Nickel (Ni) is ferromagnetic it is used in making Alnico magnets (consisting of aluminium, nickel, and cobalt). Note that the U.S. five cent coin called a “Nickel” is made of 75% copper and 25% Nickel (Ni). Even though it contains Nickel (Ni), a ferromagnetic material, they aren’t visibly attracted to magnets.In fact, they don’t interact with magnets like many other non-magnetic materials.

- It may be that the Nickel (Ni) in the nickel coin somehow disrupts the electrical currents. This seems possible since adding Nickel (Ni) to Iron, Carbon, and Chromium a form of stainless steel is created that is not magnetic even though it contains Iron. But dimes and quarters have Nickel as well, just less.

Nickel Nickel belongs to the transition metals and is hard and ductile. Pure nickel, powdered to maximize the reactive surface area, shows a significant chemical activity, but larger pieces are slow to react with air under standard conditions because an oxide layer forms on the surface and prevents further corrosion (passivation).
