Yes, this is Seaborg IAM, which I have a periodic table here.

仮定法過去

It probably be helpful if I pointed out to you.

It's right down here more or less in the middle, but for me, much towards the bottom.

This isn't a row of elements that are really quite special because these guys come after the land.

Tonight is an actor nights Which of these two rows down here on these elements are special because they don't hang around very long.

These elements are actually really unstable, and they decay.

So if you want to do anything with these, you've got to actually make the elements.

You can't just go to a chemical company and buy a job of them, you've actually gonna make them, and then you've gotta turn them into a compound that you're interested in and analyze it very, very quickly.

And some of these elements they can come and go within 8 10 15 seconds minutes.

You've made them what you want to do with the wealthy answer could be.

Let's make some interesting molecules out of them that we can study and therefore learn about some of the properties that these elements have because of the minute, because there's so little known about them because A they're very difficult to make.

And even if you do make them, they come and go so quickly.

We don't have expect very much experimental evidence to help to validate the theoretical models we've got.

The theories are really great, but we need to know that they're accurate.

And so, for example, Seaborg IAM should be very similar to analogous Group six metals higher up like tongue stern, Lipton, um, and chromium.

These air very well known, quite well understood elements.

You can make nice, stable compounds out of them that will hang around for weeks, months and years on.

You expect certain periodic trends to occurs.

You go down that group from chromium molybdenum to tongue stone on.

The question is what then happens when you go to the really super heavy Seaborg IAM in the next road down, and so you can predict what you might expect.

But what you need to do is go out and do some experiments to help validate that theory.

So the news is that of a search team prepared some Seaborg iam and this is a really elegant reaction.

They take some curium, which is element number 96 on.

They smash some neon into it, which is element number 10 on that gives you together Element 106 which is Seaborg IAM.

Now the clock's ticking because already they're going to start to fall to bits.

And so the answer is, Well, the question rather is What are you gonna do on this particular piece of research is really elegant because what it does is it generates the seaboard GM atoms and very quickly reacts them with carbon monoxide.

And the thing about carbon monoxide is it Kam bond to metal atoms?

In fact, this is one of the reasons why carbon monoxide is no good for humans.

If you inhale it, it sticks onto the iron in your hemoglobin and stops oxygen being transported around your body.

But in this case, this has been used to our advantage that you can make a Seaborg IAM with six carbon monoxide.

This is really helpful because now it turns out that this molecule is volatile on because it's volatile.

You can get it into the gas face quickly whip it off to a detector and then confirm that you've made it.

The reason it's important is it's a volatile compound that you can examine on.

You had expected to be very similar to the analogous chromium, molybdenum and tungsten carbon isles.

On importantly, they've bean known for many decades, and we understand their properties very well.

And indeed, earlier today we were just sublime ing some group six metal carbon isles just to show how they go from being a solid into the gas phase.

And then they come back out again, is a lovely, crystalline solid.

The problem is, you can't make anywhere near as much of the Seaborg Yume Carbonell, and it doesn't hang around long enough to go and put it in a jar.

So the idea behind the project is that you make the analogous militant and tungsten systems in Sichuan the same system.

And then when you do it with Seaborg, um, you know what you're looking for?

And through a very interesting on advanced, ever raised, very elegant work, you can then detect the Seaborg am Carbon Al coming out of this system where you've made the atoms of Seaborg iam How did the carbon monoxide and then fired it down to a detector so that they got a bunk of detectors which they have toe calibrate and they do all sorts of control experiments.

My understanding is one of the ways they were looking out to make sure they had the Seaboard game is that Seaborg iam decays through a certain number of processes, which I think a fairly well understood and you can predict on.

This series of transformation shows up in the detectors on nothing like that can happen when there's no Seaborg iam around.

So if it does occur, you know it has to be down to the sea.

I can easily understand the reason to create a molecule involving Seaborg, Um, in order to test the theories of what will happen, we're at theory's correct.

Harder to understand, perhaps, is why it's even worth having good, solid theories of what see Borgen will dough because see, Borgen will always be something that falls apart doesn't exist for very long.

So do we need a huge wealth of knowledge about.

It's not like it's gonna help other chemists because no one will work with this thing anyway.

Now, while I disagree with you there, actually, I think it does help other chemists because pot actually the theory aspect.

You can't overstate how important that is, because we are only as good as our understanding of the natural world around us.

And that's a bit like saying Mars is a long way away.

And so therefore, I don't care what goes on there.

You should care what goes on there because it will inform you about the basic principles and the laws that our universe operates under.

And so when you read the paper about this seaboard Carbonell, there's a discussion about how well the carbon monoxide bond to the metal, and will it be stronger or weaker than the analogous chromium, molybdenum and tungsten systems?

Now, this is really important to remember.

I've already said carbon monoxide will bond to iron and poison you.

We need to understand how these types of molecules do interact with these metal centers because this informs our understanding of chemistry in a much broader context so low it seems like a really specialist.

Very unusual thing that no one would care about.

It's actually got quite profound implications for broader understanding of chemistry.

Finally, I guess finally, it got approved in 1997 and it got approved soon enough.

So Seaboard could stand at the periodic table like this and point to his element.

 And we were so happy that he was still alive and could point here, This is Steve Organ.
