Copper element has 29 protons, 35 neutrons and 29 electrons.
Copper is a solid metal at room temperature, melting point 1084 ̊C.
Copper element is easy to lose 1 or 2 eletrons, and becomes Cu1+ or Cu2+ ions.
» Common Copper compounds:
• Copper(I) Oxide, Cu2O
• Copper(II) Oxide, CuO
• Copper(II) Hydroxide, Cu(OH)2
• Copper(II) Sulfate, CuSO4
• Copper(I) Carbonate, Cu2CO3
• Copper(II) Nitrate Hexahydrate, Cu(NO3)2.6H2O
• Copper(II) Nitrate, Cu(NO3)2
• Copper(II) Sulfate Pentahydrate, CuSO4.5H2O
• Copper(II) Iodide, CuI2
Example Reactions:
• Cu + 2AgNO3 = Cu(NO3)2 + 2Ag
• Cu + AgNO3 = CuNO3 + Ag
• Fe + CuSO4 = Cu + FeSO4
• Cu + 2H2SO4 = CuSO4 + 2H2O + SO2
• 4HNO3 + Cu = Cu(NO3)2 + 2NO2 + 2H2O
• Mg + CuSO4 = MgSO4 + Cu
• CuSO3 + Zn = ZnSO3 + Cu
• Fe + CuCl2 = FeCl2 + Cu
• Mg + Cu(NO3)2 = Mg(NO3)2 + Cu
• Cu + 2HCl = CuCl2 + H2
