What does actinium react with?
Actinium makes a new substance with 7 other elements and chemicals in our lab:
- Actinium + OxygenActinium oxide 4Ac + 3O₂ → 2Ac₂O₃ · Only in a special nuclear lab (it is radioactive) · Try it
- Actinium + FluorineActinium fluoride 2Ac + 3F₂ → 2AcF₃ · Only in a special nuclear lab (it is radioactive) · Try it
- Actinium + ChlorineActinium chloride 2Ac + 3Cl₂ → 2AcCl₃ · Only in a special nuclear lab (it is radioactive) · Try it
- Actinium + BromineActinium bromide 2Ac + 3Br₂ → 2AcBr₃ · Only in a special nuclear lab (it is radioactive) · Try it
- Actinium + IodineActinium iodide 2Ac + 3I₂ → 2AcI₃ · Only in a special nuclear lab (it is radioactive) · Try it
- Actinium + WaterActinium hydroxide + hydrogen gas 2Ac + 6H₂O → 2Ac(OH)₃ + 3H₂ · Only in a special nuclear lab (it is radioactive) · Try it
- Actinium + Hydrochloric AcidActinium chloride + hydrogen gas 2Ac + 6HCl → 2AcCl₃ + 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 18 of the others. 21 pairings have never been tried, because not enough atoms have ever existed.
