Good work again mate! Your videos really are quality educational resources.

[@AlbertoMelappioni]

Thanks for these videos, they are always very interesting!

[@Muonium1]

More spectroscopy videos and electronic transition explanations of color!! 👍🏻 📈

Being a radioactive compound it's no surprise that we don't hear about nor see potassium pertechnetate very often unlike it's other two analogues potassium permanganate and potassium perrhenate.

[@Havron]

Technically, they are all radioactive. ;-)

[@brfisher1123]

@@Havron I deliberately made the slight error of considering potassium permanganate and potassium perrhenate non-radioactive to see if someone would catch that. Glad you caught on that lol 😂😂 Potassium perrhenate in particular would have been interesting to see tested in a beta spectrometer.

Pertechnate seems to have some interesting properties as an oxidizer based on the table at 3:00 ;the phenomenon of radius contraction is on full display with those f orbitals on the perrhenate and it also shows on the redox potential, if we compare Pertechnate and iodine it's actually somewhat similar in terms of shell config and potential but far smaller. Iodine and Chlorates are often seen as being chemical twins, I wonder if you could use TcO4 in applications where you use DMP or similar oxidants. People have been building some interesting coordination complexes with manganese for this, unfortunately all the papers I found (from my admittedly very quick look) all just focused on immobilizing all those tasty Pertechnates via reduction rather than doing any fun chemistry with them. Have you seen any organic chemistry being done on Technetium other than just building complexes or immobilizing fission products? It's low enough in radioactivity that it must have some practical organic chemistry applications I am now really curious about. (Also so disappointed its a gray powder now, I vote we change it to a glowing neon purple compound)

[@SimonsNuclearchemistry]

Would also love a nicer colour xD Yes there are a lot of organic Tc Compounds. Especially with interrest in medical Tc-99m. The Man of interrest is "Prof. Dr. Roger Alberto" the Technetium pope! 😅 He recently retired but man his working group was on fire when it comes to Tc compounds.

[@user-pr6ed3ri2k]

when is perbohrate

[@Fr3ak_MM8BDM]

Never seen actual KTcO4 before, thanks for this! Was that your own sample or an image you found?

[@brfisher1123]

I'm guessing it's because potassium pertechnetate is quite radioactive unlike it's other two analogues and people don't often like to mess with highly radioactive materials being often terrified of them.

[@SimonsNuclearchemistry]

I work in a Nuclear chemistry lab and we do Technetium chemistry^^ I will show some of it in the future

[@SimonsNuclearchemistry]

@@brfisher1123 its very active but Technetium emitts soft beta radiation. So basically very little danger for any chemist working with it

[@Fr3ak_MM8BDM]

@@SimonsNuclearchemistry Hopefully in the far future we're able to get a sample of bohrium to run the same experiments but it seems unlikely 😅

[@brfisher1123]

@@SimonsNuclearchemistry Oh yeah, I've heard of those externally safe soft beta emitters like the tritium found in those commonly available tritium lights.

Hi Simon, my name is Matyas and i study at Botičská Grammar School in Czech republic. My school requires as part of the final exam to write An Academic research paper and i chose o about Uranium from mines from Příbram and tis chemistry, i would appreciate your help due to your expertise. So please may i have your e-mail for easier and more formal comunication? Thank you for response:)

[@SimonsNuclearchemistry]

Since I am based in Germany, I am required to give my contact information in the KZbin Info Box about my channel. So you'll find it there ;D
