What does technetium react with?
Technetium makes a new substance with 3 other elements and chemicals in our lab:
- Technetium + OxygenTechnetium(VII) oxide 4Tc + 7O₂ → 2Tc₂O₇ · Only in a special nuclear lab (it is radioactive) · Try it
- Technetium + FluorineTechnetium(VI) fluoride Tc + 3F₂ → TcF₆ · Only in a special nuclear lab (it is radioactive) · Try it
- Technetium + ChlorineTechnetium(IV) chloride Tc + 2Cl₂ → TcCl₄ · 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 22 of the others. 21 pairings have never been tried, because not enough atoms have ever existed.
