What does radon react with?
Radon makes a new substance with 1 other element or chemical in our lab:
- Radon + FluorineRadon difluoride Rn + F₂ → RnF₂ · Only in a special nuclear lab (it is radioactive) · Try it
Nothing happens when it's simply mixed with 97 of the others. 21 pairings have never been tried, because not enough atoms have ever existed.
