What does einsteinium react with?
Einsteinium makes a new substance with 6 other elements and chemicals in our lab:
- Einsteinium + OxygenEinsteinium oxide 4Es + 3O₂ → 2Es₂O₃ · Only in a special nuclear lab (it is radioactive) · Try it
- Einsteinium + FluorineEinsteinium fluoride 2Es + 3F₂ → 2EsF₃ · Only in a special nuclear lab (it is radioactive) · Try it
- Einsteinium + ChlorineEinsteinium chloride 2Es + 3Cl₂ → 2EsCl₃ · Only in a special nuclear lab (it is radioactive) · Try it
- Einsteinium + BromineEinsteinium bromide 2Es + 3Br₂ → 2EsBr₃ · Only in a special nuclear lab (it is radioactive) · Try it
- Einsteinium + IodineEinsteinium iodide 2Es + 3I₂ → 2EsI₃ · Only in a special nuclear lab (it is radioactive) · Try it
- Einsteinium + Hydrochloric AcidEinsteinium chloride + hydrogen gas 2Es + 6HCl → 2EsCl₃ + 3H₂ · 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 19 of the others. 21 pairings have never been tried, because not enough atoms have ever existed.
