Atomic Number 28 Symbol

The atomic number of an element is equal to the total number of protons in the nucleus of the atoms of that element. The atomic number can provide insight into the electronic configuration of the element. For example, carbon has an electron configuration of He 2s 2 2p 2, since its atomic number is 6. Nickel (Ni, atomic number 28) is an element. Region of the periodic table (symbol Ni). Nickel is an element, Atomic number 28, symbol NI What is a atomic number in a element?

The American nickel is made up of a nickel-copper alloy. Nickel is also used in nickel-metal-hydride (Ni-MH) rechargeable batteries.

History

Atomic Number 28 Means

Atomic number 28 symbol

From the German word Nickel (Satan), and from kupfernickel, Old Nick's copper. Cronstedt discovered nickel in 1751 in kupfernickel (niccolite).

Sources

Nickel is found as a constituent in most meteorites and often serves as one of the criteria for distinguishing a meteorite from other minerals. Iron meteorites, or siderites, may contain iron alloyed with from 5 percent to nearly 20 percent nickel. Nickel is obtained commercially from pentlandite and pyrrhotite of the Sudbury region of Ontario, a district that produces about 30 percent of the world's supply of nickel.

Other deposits are found in New Caledonia, Australia, Cuba, Indonesia, and elsewhere.

Properties

Nickel is silvery white and takes on a high polish. It is hard, malleable, ductile, somewhat ferromagnetic, and a fair conductor of heat and electricity. It belongs to the iron-cobalt group of metals and is chiefly valuable for the alloys it forms.

Uses

It is extensively used for making stainless steel and other corrosion-resistant alloys such as Invar(R), Monel(R), Inconel(R), and the Hastelloys(R). Tubing made of copper-nickel alloy is extensively used in making desalination plants for converting sea water into fresh water.

Nickel, used extensively to make coins and nickel steel for armor plates and burglar-proof vaults, and is also a component in Nichrome(R), Permalloy(R), and constantan.

Nickel gives glass a greenish color. Nickel plating is often used to provide a protective coating for other metals, and finely divided nickel is a catalyst for hydrogenating vegetable oils. It is also used in ceramics, in the manufacture of Alnico magnets, and in the Edison(R) storage battery.

Isotopes

The sulfate and the oxides are important compounds. Natural nickel is a mixture of five stable isotopes; nine other unstable isotopes are known.

Handling

Exposure to nickel metal and soluble compounds (as Ni) should not exceed 0.05 mg/cm3 (8-hour time-weighted average per 40-hour work week). Nickel sulfide fume and dust is recognized as being potentially carcinogenic.
