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.

This is a list of chemical elements, sorted by atomic mass (or most stable isotope) and color coded according to type of element. Each element's atomic number, name, element symbol, and group and period numbers on the periodic table are given. The number in parenthesis gives the uncertainty in the 'concise notation' dis given in parenthesis next to the least significant digits to which it. Symbol: Ni Atomic Number: 28 Atomic Mass: 58.6934 amu Melting Point: 1453.0 °C (1726.15 K, 2647.4 °F) Boiling Point: 2732.0 °C (3005.15 K, 4949.6 °F) Number of Protons/Electrons: 28 Number of Neutrons: 31 Classification: Transition Metal Crystal Structure: Cubic Density @ 293 K: 8.902 g/cm 3 Color: white Atomic Structure.

Iron objects can be plated with nickel for corrosion resistance.

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12) Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol. Weights of atoms and isotopes are from NIST article. It provides atomic mass, mass excess, nuclear binding energy, nucleon separation energies, Q-values, and nucleon residual interaction parameters for atomic nuclei of the isotope Ni-92 (Nickel, atomic number Z = 28, mass number A = 92).

The principal ores of nickel are nickelite (NiAs), millerite (NiS), and pentlandite ((Ni,Fe)S. Nickel forms a sulfide mineral with arsenic called gersdorffite. Nickel forms another arsenide called nickel-skutterudite, NiAs_2-3. The sulfide formed with antimony is called ullmannite. Copper, cobalt and nickel join in the sulfide carrollite, Cu(Co,Ni)₂S₄. Cobalt and nickel form the sulfide siegenite, CoNi₂S₄. Nickel is often found in association with iron and sometimes forms the compound Ni₃Fe, called awaruite in its mineral form. Nickel-iron meteorites are fairly common. A major source of nickel is the Sudbury Basin in Canada associated with the second largest meteoritic impact crater on the Earth.

Nickel is used in alloy with gold to make 'white gold' for jewelry use.
