Cucl2 Research Paper

Satisfactory Essays
When writing chemical formulas for compounds with transition metals, the transition metal will always come first. For the copper(II) chloride example, you first write “Cu” for copper, followed by “Cl” for chloride. Since you determined you need two chloride ions when you balanced the compound, the complete chemical formula should read “CuCl2.” If you have a transition metal in a compound with a polyatomic ion, the polyatomic ion needs to go in parentheses. For example, chromium(II) bicarbonate’s formula is “Cr(HCO3)2.” Notice the subscript for the polyatomic ion is located outside of the parentheses.
