Nickel is a hard, malleable, ductile, lustrous, silvery white, ferromagnetic
metallic element in Group VIII of periodic table; atomic number 28; atomic mass
58.69; melting point ca 1,453°C; boiling point ca 2,732°C; specific gravity
8.902 g/cm3; valence 0, 1, 2, 3; electronic config. 2-1 or 4s 23ds8. It is a
fairly good conductor of heat and electricity. It takes on a high polish. Its
magnetic properties and chemical activity resemble iron and cobalt. It has
properties to form easily a number of alloys. Some of the metals that nickel can
be combined with are iron, copper, chromium, and zinc. Most of these nickel
compounds have blue or green color. Nickel dissolves in dilute acids slowly but
will be passive with nitric acid like iron. Fine nickel powder adsorbs hydrogen
and is in the hydrogenation of oils. Nickel alloys are used in making coins and
heat exchange items like valve. The Most of nickel is used to make stainless
steel as a protective and ornamental coating for less corrosion. Nickel is
combined with many other elements, including chlorine, sulfur, and oxygen. Most of these nickel compounds dissolve easily in water and have a
characteristic green or blue color with no characteristic odor or taste. Nickel
compounds are used in plating, coloring ceramics, making some batteries, and as
chemical reaction catalysts.
