What does cadmium react with?
Cadmium makes a new substance with 12 other elements and chemicals in our lab:
- Cadmium + OxygenCadmium oxide 2Cd + O₂ → 2CdO · When heated · Try it
- Cadmium + FluorineCadmium fluoride Cd + F₂ → CdF₂ · At room temperature · Try it
- Cadmium + PhosphorusCadmium phosphide 3Cd + 2P → Cd₃P₂ · When heated · Try it
- Cadmium + SulfurCadmium sulfide Cd + S → CdS · When heated · Try it
- Cadmium + ChlorineCadmium chloride Cd + Cl₂ → CdCl₂ · When heated · Try it
- Cadmium + ArsenicCadmium arsenide 3Cd + 2As → Cd₃As₂ · When heated · Try it
- Cadmium + SeleniumCadmium selenide Cd + Se → CdSe · When heated · Try it
- Cadmium + BromineCadmium bromide Cd + Br₂ → CdBr₂ · When heated · Try it
- Cadmium + TelluriumCadmium telluride Cd + Te → CdTe · When heated · Try it
- Cadmium + IodineCadmium iodide Cd + I₂ → CdI₂ · When heated · Try it
- Cadmium + PoloniumCadmium polonide Cd + Po → CdPo · Only in a special nuclear lab (it is radioactive) · Try it
- Cadmium + Hydrochloric AcidCadmium chloride + hydrogen gas Cd + 2HCl → CdCl₂ + H₂ · At room temperature · Try it
It also blends into a mixture, like an alloy, with 74 other metals when melted together.
Nothing happens when it's simply mixed with 12 of the others. 21 pairings have never been tried, because not enough atoms have ever existed.
