Is Technetium a Naturally Occurring Element?

[@Nismo11]

I must say, I greatly appreciate the comprehensive contextualization expressed in this video! It really sets this video apart from others which may not give thorough context to niche topics. Context is very important! Thank you! :D

[@TSW369]

Awesome That's some expert talk! Very informative.

[@ChemSurvival]

Thanks for the kind words. I love making these videos and hope to get back to it sometime in the future. In the meantime, be sure to check out the rest of the channel for more!

Very interesting! Really enjoy your KZbin channel and Wondrium courses.

[@ChemSurvival]

I'm so glad you enjoy my lectures! Thanks for watching :-)

[@alexeynava3086]

This is the most unexpected thing hahaha . I love natty or not videos as well. This was awesome. Been following you for many years. You have helped tons and I’m thankful for it. Keep doing the great work you do!

[@ChemSurvival]

Thanks for the comment and the kind words. That whole fitness community on KZbin is so entertaining to watch. I will probably do a few 'Molecule Monday' videos on test, tren and other well-known "naughty sauce" compounds sometime, so stay tuned!

@@ChemSurvival sounds great. It sure is a very interesting topic to dive in from a chemistry point of view. It would be nice to hear a discussion about the expected properties of some of those molecules given their main functional groups. Keep killing it !

This explains things better than most I've heard. Where they said a flat-out no for the entire universe, which seemed a little off to me. The fact that it exists mostly in Stars and in Decaying isotopes is a little ore believable to me :) Either that or XT's Mined all the major deposits away back when we where still figuring things out beyond hunting and gathering.

Great video! Next question: How is the second "t" in "technetium pronounced?

[@fukpoeslaw3613]

I say: ts the second t is pronounced ts

If you can't see Atoms how do you figure out what the diverse molecule structures look like? I'm a new Chemistry Student in Austin ,Texas. My first semester starts Jan. 18th, 2022 thank you for videos.👍🙃🧐🤓🙃😄🙃🧐🙃👍

Most Stars (Sun like stars) stop the fusion process when element 26 is formed (Iron). Therefore, all elements produced after element 26 (Iron) are much rarer in nature because they are created in super nova 💥 (when stars self destruct 😢).

[@Nismo11]

Or even neutron star mergers! The can make supernovae look like party snaps in comparison. edit: I'd also like to point out, just as was stated in the video, there have been spectral lines of Tc observed in intermediate-mass stars during their AGB phase. Although this isn't the core of the star fusing elements, rather Tc forming due to the slow neutron capture process.

It still confuses me why technetium and astatine are where they are on the table, given their extreme rarity. I know I don’t know enough about the elements, but I just figured either they’d be more abundant, or many others on the table would be just as rare.

[@Nismo11]

It's simply due to their stability. They decay quite quickly, so it's just not there very long. Astatine decays quite rapidly, with a half-life on the order of a few hours, whereas technetium's most stable isotope, technetium-99 takes something like 211,000 years until approximately half of it beta decays into ruthenium-99. Even still, this makes it exceedingly rare.

The element 43 can be used in safe nuclear batteries 😮 + Artificial intelligence 😮 + electric vehicles 😮 or you just use element 92 (uranium) 😅.

[@Nismo11]

Historically, plutonium-238 has been used in radioisotope tec generators, using the peltier effect, but it's exceedingly expensive, and quite dangerous. I'm not exactly sure how you'd integrate this into AI, or vehicles. I'm also a bit confused on how you could use Tc-99 to make a battery. It's not really energetic enough to use in an RTG. Of course, there's the tried and true method of of using U-235 to boil water and spin a turbine at a power plant to make electricity. This can then be transformed a few times and sent over to you car to charge a lithium-ion battery, or power a computer running an AI neural network via mains power! :D

@@Nismo11 unless you found a way to directly harvest electrons from decay rather than thermal generation i dont see 43 being particularly effective

[@Nismo11]

@@SlavTiger Right. That's why I'm still a bit confused by the original poster's comment.

Neil the grass Tyson doesn't know about natural occuring technetium, someone needs to tell him
