The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
Nickel(II) sulfate, or just nickel sulfate, usually refers to the inorganic compound with the formula NiSO 4 (H 2 O) 6. This highly soluble turquoise coloured salt is a common source of the Ni 2+ ion for electroplating .
A binary compound of nickel contains one other element. Substances that contain only nickel atoms are not actually compounds. In a noble gas matrix, nickel can form dimers, a molecule with two nickel atoms: Ni 2. [1] Ni 2 has a bonding energy of 2.07±0.01 eV. For Ni 2 + the bond energy is around 3.3 eV. Nickel dimers and other clusters can ...
Nickel sulfide is any inorganic compound with the formula Ni x S y. These compounds range in color from bronze (Ni 3 S 2) to black (NiS 2). The nickel sulfide with simplest stoichiometry is NiS, also known as the mineral millerite. From the economic perspective, Ni 9 S 8, the mineral pentlandite, is the chief source of mined nickel.
IUPAC states that, "As one of its major activities, IUPAC develops Recommendations to establish unambiguous, uniform, and consistent nomenclature and terminology for specific scientific fields, usually presented as: glossaries of terms for specific chemical disciplines; definitions of terms relating to a group of properties; nomenclature of chemical compounds and their classes; terminology ...

The known salts include (NH 4) 2 Ni 2 (SO 4) 3, K 2 Ni 2 (SO 4) 3 and Rb 2 Ni 2 (SO 4) 3, and those of Tl and Cs are predicted to exist. Some minerals are double salts, for example Nickelzippeite Ni 2 (UO 2 ) 6 (SO 4 ) 3 (OH) 10 · 16H 2 O which is isomorphic to cobaltzippeite , magnesiozippeite and zinczippeite , part of the zippeite group.
