What does platinum react with?
Platinum makes a new substance with 7 other elements and chemicals in our lab:
- Platinum + FluorinePlatinum(IV) fluoride Pt + 2F₂ → PtF₄ · When heated · Try it
- Platinum + SiliconPlatinum silicide Pt + Si → PtSi · Only in a very hot furnace · Try it
- Platinum + PhosphorusPlatinum phosphide Pt + 2P → PtP₂ · When heated · Try it
- Platinum + SulfurPlatinum(II) sulfide Pt + S → PtS · When heated · Try it
- Platinum + ChlorinePlatinum(II) chloride Pt + Cl₂ → PtCl₂ · When heated · Try it
- Platinum + ArsenicPlatinum arsenide (sperrylite) Pt + 2As → PtAs₂ · When heated · Try it
- Platinum + PoloniumPlatinum(IV) polonide Pt + 2Po → PtPo₂ · Only in a special nuclear lab (it is radioactive) · Try it
It also blends into a mixture, like an alloy, with 73 other metals when melted together.
Nothing happens when it's simply mixed with 18 of the others. 21 pairings have never been tried, because not enough atoms have ever existed.
