Heavy metals are elements with an atomic weight ranging from 63.5 to 200.6 g/mol and a density greater than 5 g/cm 3 (Srivastava and Majumder, 2008).Certain heavy metals such as zinc (Zn), cobalt (Co), copper (Cu) and iron (Fe) are essential at a trace concentration to maintain life by involving in diverse biological … WebJun 7, 2024 · In the copper(I) sulfide, the copper is +1 and the sulfur -2. The oxidation states of the elements oxygen (in the gas) and copper (in the metal) are 0. In sulfur dioxide, the oxygen has an oxidation state of -2 and the sulfur +4. That means that both the copper and the oxygen have been reduced (decrease in oxidation state).
