Copper Sulfide

  • What is the chemical formula of copper (II) sulfide ...

    Apr 30, 2008· Best Answer: copper (II) has a valency of +2, and sulfide a valency of -2. so we can say that since one has an excess of 2 electrons (S), and the other has lost two electrons (Cu), a single atom of copper will combine with a single atom of sulfide. we derive the formula : CuS
