Cd3(PO4)2
The chemical formula for cadmium phosphate is Cd3(PO4)2.
To determine the chemical formula, you need to know the valency or oxidation state of each element and use it to balance the charges of the ions.
1. Determine the valency of cadmium (Cd). Cadmium is a transition metal located in Group 12 of the periodic table, which means it can exhibit different valencies. In this case, cadmium has a valency of +2.
2. Determine the valency of phosphate (PO4). Phosphate is a polyatomic ion with a valency of -3. This means it carries a charge of -3.
3. Balance the charges. Cadmium has a valency of +2, while the phosphate ion has a valency of -3. The number of cadmium ions (Cd2+) needed to balance the charge of the phosphate ion (PO4 3-) is 3 Cd2+ ions.
Therefore, the chemical formula of cadmium phosphate is Cd3(PO4)2, which indicates that three cadmium ions combine with two phosphate ions to form the compound.
