What does radium react with?
Radium makes a new substance with 9 other elements and chemicals in our lab:
- Radium + NitrogenRadium nitride 3Ra + N₂ → Ra₃N₂ · Only in a special nuclear lab (it is radioactive) · Try it
- Radium + OxygenRadium oxide 2Ra + O₂ → 2RaO · Only in a special nuclear lab (it is radioactive) · Try it
- Radium + FluorineRadium fluoride Ra + F₂ → RaF₂ · Only in a special nuclear lab (it is radioactive) · Try it
- Radium + SulfurRadium sulfide Ra + S → RaS · Only in a special nuclear lab (it is radioactive) · Try it
- Radium + ChlorineRadium chloride Ra + Cl₂ → RaCl₂ · Only in a special nuclear lab (it is radioactive) · Try it
- Radium + BromineRadium bromide Ra + Br₂ → RaBr₂ · Only in a special nuclear lab (it is radioactive) · Try it
- Radium + IodineRadium iodide Ra + I₂ → RaI₂ · Only in a special nuclear lab (it is radioactive) · Try it
- Radium + WaterRadium hydroxide + hydrogen gas Ra + 2H₂O → Ra(OH)₂ + H₂ · Only in a special nuclear lab (it is radioactive) · Try it
- Radium + Hydrochloric AcidRadium chloride + hydrogen gas Ra + 2HCl → RaCl₂ + H₂ · 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 16 of the others. 21 pairings have never been tried, because not enough atoms have ever existed.
