Oganesson – Periodic Table of Videos

published on July 17, 2020

At the time of making this video December 2016 it is probably a unique time for the periodic table in any of your lifetimes because the name of four different elements Nihon IAM moscovia m– tennyson and agony song' have all been announced

Simultaneously and it is extremely unlikely that this will happen again four elements at once for a very long time if ever now agonise on element 118 is special for a number of different reasons the first thing which makes it

Very special is that it is the last element on the Mendeleev form of the periodic table it completes a row the second point is that it is only the second element that has been named after a living scientists do Gustav Google

Google geo and the third point is that it is a noble gas and so will have particularly interesting properties and fourthly and that in which I find most interesting is that there was a case of scientific fraud or at least scientific

Irregularity earlier on when a lab claimed to discover this element and then had to retract that is say they were wrong so this element agonism has been named in honor of the very famous nuclear chemist or perhaps

Physicists in russia yurid salah kovitch salaka which means son of Sherlock agony seon he is a pioneer and very longtime researcher in Dubna the research centre to the north of Moscow the only other element that was named after a living

Scientist with seaborgium named after Glenn T Seaborg who was the discoverer of plutonium and several other elements there is a slight difference because Agra Nissan does not have quite the whole of agonist Ian's surname in it

But I think this is a trivial difference and it is often been said that having an element named after you is much better than winning a Nobel Prize because Nobel Prize winners get forgotten pretty quickly whereas your name is on the wall

Of nearly every school room in the world well at least every science lab in the world so it's a terrific Memorial there's a bit of argument whether Einstein was told on his deathbed that an element was going to be named after

Him but the formal naming was after his death and anyway he didn't discover all contribute to the discovery of the element so I don't think that counts I have not yet met your it solar coverage but I hope that we will meet in 2017 and

If we do there will be plenty of videos to market I think it is a terrific name and I fully support it it is interesting because the name ends in on Oh n which is the ending that is used for the names of all the noble gases except helium

Which does end with I um the interesting thing is that as these gases get heavier they are going to be much less volatile that is there you're going to be harder if you like for them to take off like it's harder for a jumbo jet to take off

Than for a glider if anything the evidence for element 118 is more secure than for most other elements in this region of the periodic table and there is a reason why people want to be absolutely sure

Because in the late 1990s there was a claim from America that element 118 had been synthesized you have to understand that the output from an experiment it's huge quantities of data from a detector stored in a computer and then you have

Data analysis programs that look for the results of Caze of these different elements and all being well you might discover one or two or three decays but not very many what appears to have happened in this case is

That one of the researchers about that garyun physicist called ninive appears to have in some way either changed the date or changed the algorithm so it appeared that element 218 had been discovered after two or three years it

Was decided that the experiments could not be duplicated other labs tried to do it and couldn't find any trace from their particular recipe and also even looking at the original data people couldn't reproduce the analysis and so

The original paper was withdrawn I think this is an enormous ly important lesson to all of you who doing science you should enjoy the results you get and you should not try and fiddle the results or massage the data to try and make them

Better because first of all if you're found out it will destroy your reputation but most important of all the joy of doing science is to understand nature to understand how matter behaves and if you cheat you don't understand

Anything so it removes all the joy and excitement of doing science the other reason that people have got so excited about element 118 agonism is that it completes the Mendeleev periodic table you have a nice

Complete row and it looks as if it's finished and several people already asked me is there going to be any more element 119 element 120 and quite conveniently my answer is on this Japanese tea towel where you can see if

You draw the periodic table like this it's not actually finished at 118 because 119 and 100 20 are there on the right-hand side so but our the way we couldn't even if we use the traditional Mendeleev style one

We could just start a new row couldn't wait yes of course we could start a new row the advantage of this format is that it shows us that there's nothing special about hundred and eighteen being the last one and it gives us encouragement

To keep going you could of course a in the Mendeley format well you know it's complete we're never going to be able to do it whereas if you look here you can see is quite reasonable I very much hope that in the next year or so that the

First glimmers of a result for 119 or more probably 120 because if you look at the history of the periodic table the even elements seem to be discovered before the odd ones I think there is a real chance that we will keep going and

Nobody will be more excited than I am well perhaps you read selectively which again yes Ian maybe even more excited five years in the job can you imagine what that must be like yeah that's nothing because the longest

Serving the Foreign Secretary of the Royal Society is that man behind us very famous scientist this is Thomas Young and my great hero because he was such a good foreign secretary now professor clearly I don't have to introduce you to

Keith because here's a little secret viewers
