Copper monosulfide is a chemical compound of copper and sulfur. It occurs in nature as the dark indigo blue mineral covellite. It is a moderate conductor of electricity.
Copper(II) sulfide is an inorganic salt with the formula CuS. It can be found in nature as the mineral covellite. Copper(II) sulfide is one of many copper sulfur binary compounds. The compound is slightly conductive and has potential uses in photovoltaics and as a catalyst.
Copper(II) sulfide can be made by bubbling H2S gas through a solution with a copper(II) cation like basic copper carbonate or copper(II) sulfate.

Another method of creating copper(II) sulfide is melting a mixture of copper(I) sulfide and an excess of sulfur together.
Copper(II) sulfide is a chemical compound of copper and sulfur. It occurs in nature as the mineral covellite. Copper is a chemical element with the symbol Cu and atomic number 29. Copper is an essential elements in plants and animals as it is required for the normal functioning of more than 30 enzymes. It occurs naturally throughout the environment in rocks, soil, water, and air.
The trick here is to realize that the Roman numeral used to name this ionic compound tells you the oxidation state of the metal.

In this case, you know that in copper(II) sulfide, the copper cation carries.
Sulfur is located in group 16 of the Periodic Table, which implies that it forms anions. You can thus say that you're dealing with the copper(II) cation,

As you know, ionic compounds are electrically neutral. This means that the overall positive charge of the cations must be balanced by the overall negative charge of the anions.

You can thus say that a formula unit of copper(II) sulfide will contain one copper(II) cation.
Copper (II) Sulfide is available in purities from 99.5% up to 99.998% pure. Higher purity Cupric Sulfide is typically ampouled to maintain is dryness as the chemical is very sensitive to moisture in the atmosphere.
