Nickel vs Chrome
Nickel is a chemical element with atomic number 28 which means there are 28 protons and 28 electrons in the atomic structure. The chemical symbol for Nickel is Ni. The atom consist of a small but massive nucleus surrounded by a cloud of rapidly moving electrons. Nickel-78 is one of the element's heaviest known isotopes. With 28 protons and 50 neutrons, nickel-78 is doubly magic, resulting in much greater nuclear binding energy and stability despite having a lopsided neutron-proton ratio. It has a half-life of 122 ± 5.1 milliseconds. They found alloys. Even today, metals are used in plating, a coating for environmentally sensitive equipments for protection, to add a finish and a look. Nickel and Chrome are two different metals popular is metal plating/coating industry. Nickel is a d-block metal having the chemical symbol Ni. Its atomic number is 28.
The word industrial revolution reminds us of two things, and they are fuel and metals. Using metals for various purposes is clearly an indication of how advanced we are in terms of technology. Metals have unique properties. Therefore, each of the metal found on earth could be used for different applications. As time passed by, people realized that mixing two or more metals together helps re-define the idea of material usage. They found alloys. Even today, metals are used in plating, a coating for environmentally sensitive equipments for protection, to add a finish and a look. Nickel and Chrome are two different metals popular is metal plating/coating industry.
Nickel
Nickel is a d-block metal having the chemical symbol Ni. Its atomic number is 28. The appearance of pure Ni is silvery white with a slight golden tinge to it. It is hard and withstands many environmental conditions. One main feature is the anti-corrosive property due to the slow rate of oxidation. Ni was first isolated and identified as an element by 1751 by Axel Fredrik. Major Ni production sites are situated in Canada, Russia and Pacific region.
Due to the anti-corrosive nature Ni is used to plate iron and brass. It is also a part of alloys like German silver, which gives a silvery polish. Ni was also used in making coins during the past although it is replaced with cheaper metals at present. Some people also show allergic response to Ni, especially skin allergies. Only four elements are ferromagnetic under room temperature, and Ni is one of them. Apart from its applications in home appliances, automobiles, Ni is also used as an industrial catalyst in industries like margarine production.
Chrome (Chromium)
Chrome is another name for Chromium. This is also a d-block metal. It has the chemical symbol Cr, and its atomic number is 24. Chrome appears in steel gray. It is hard and brittle. This metal also can be highly polished and, therefore, used as a surface coating in many home appliances and automobile parts. Chrome can also withstand very high temperatures. Chromium is, however, a very toxic and carcinogenic compound. Chromium production sites require environmental cleanups.
Chrome plating gives a shiny, mirror like finish. It is also durable and anti-corrosive. Due to the smooth finish finger prints, marks, water spots and scratches are highly visible. This is a shortcoming of Chrome plating. Chrome is used to plate copper and steel. It is also used to make Nichrome an alloy made up of Nickel and Chrome used in hot plates, ovens and irons.
Nickel vs Chrome
• Nickel and Chrome (also known as Chromium) are two different metals.
• They are both used in metal plating. Nickel plating gives a matt finish, and Chrome gives a mirror-like finish.
• Nickel tend to discolor with time more than Chrome does.
• Nickel plating does not show finger prints, scratches etc. to the naked eye like Chromium plating does.
• Chromium/Chrome is expensive than Nickel.

History
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.

What Is The Atomic Number Of Nickel
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.
