| Reactions of Palladium |
 Reactions with air |
| Heating palladium metal with oxygen results in formation of palladium(II) oxide. |
2Pd(s) + O2(g) PdO(s) |
| Reactions with halogens |
| Careful control of the reaction between palladium metal and fluorine gas results in palladium trifluoride. |
| 2Pd(s) + 3F2(g)[Pd][PdF6](s) |
| Palladium(II) chloride is also formed in the controlled reaction of palladium metal and chlorine. Depending upon the reaction conditions, one of two different forms of PdCl2 is formed. In a related reaction palladium(II) bromide, PdBr2, is formed in the reaction of palladium metal and bromine. |
