FOUR new elements (inc Japonicium and Moscovium?) – Periodic Table of Videos

published on July 20, 2020

It's been a really good start to 2016 from the point of view of the periodic table I you pack the International Union of pure and applied chemistry has confirmed the existence of four new elements so if you look at the periodic table here we have elements 113 115 117

118 that have no names at the moment they have symbols UUP meaning 1 1 5 but they don't have a real name and what's happened is not new experiments but the committee's looking at the experimental evidence have decided that those

Elements really have been synthesized and a real so in a way it's a bit like giving a prize to the people who have done the experiments to say you've got it right before we go into possible names for these elements let me just

Remind you if you haven't watched our videos before how you make these elements if you look at the periodic table all the elements that are heavier than uranium number 92 all of these are highly radioactive and as you go along

The periodic table they become more and more radioactive even if you have some atoms they decay in fractions of a second or just a few seconds so you can't dig them out of the ground you have to make them and the way you make

Them is by taking a lighter atom but which is still quite heavy and bombarding that material with lighter atoms you do this so billions of light atoms hit every second and then every so often that's once a week for difficult

Elements once a month one of these atoms fuses into the other one so you can see it's quite a hard process and my dog toy is getting bit old so now you have a combined nucleus for example we have element 95 and

Are–some plus element calcium 2020 plus 95 makes 115 and bingo you get an atom of the element of course this atom is quite unstable so you detect it by watching it decay these elements here have been discovered in different labs

Usually but not always as a collaboration between two different laboratories and you have to understand that these are such specialized experiments that you will only find one suitable lab in a particular country and

Often most countries don't even have such labs so element 113 was first discovered in the lab in Japan we have a video in Japanese about it for our Japanese viewers so sorcery for Syria come on again Chicago gotten very

Business knee with guitarist ed and the other elements here one one five one one seven one one eight were collaborations between us lab and the research centered in Du Bois near Moscow and so the experiments were done in Dubna but the

Precursors the radioactive materials like berkelium which were the heavy element that we crushed into were prepared in america and flown over now you have to understand that the way that our u-pike operates is that after the

First lab has done the experiments they require somebody else to do the repeat of the experiments to make sure the first ones are right so although for example I might have done the first experiments I don't

Synthesize in elements but just as an example then somebody else will confirm my results so it's only polite and I think nice to talk to the other people before choosing a name there are certain rules you can name it after places

Countries people but the important thing is the person has to be a scientist who's dead my feeling is and I have no idea what the names to be but I think element 1 1 3 is likely to have a Japanese name because

The Japanese lab at RIKEN has been told they can choose the name there is a fruit which some of you may know called japonica so you could imagine a name something like japonicum based on japan it would have the symbol j-p-j doesn't

Appear on the periodic table yet so that would be really nice first sometimes Germans call iodine by the letter J but most periodic tables don't have a J there is some internet chatter and I've heard rumors that element 1 1 5 will be

Called moscovia after Moscow I think that would be really good though of course the symbol M o has already gone for molybdenum I like moscovia because my father was born in Moscow I have also suggested that element 1 1 7

Should be called after Richard Fineman the famous physicist fine manian but some viewers already had said that by Manian should be left for element 132 which Fineman predicted might be stable so we'll have to see

I feel probably that the most thoughts will be given by people to element 118 because that's the highest number currently on the periodic table and I have no idea what they will choose you will see all over the press people are

Saying the periodic table is now complete which in a way it is that we've finished this row of the periodic table the seventh row as you go down 1 2 3 4 5 6 7 but I see this just at the beginning the field is now open can physicists now

Synthesize elements which will start row number 8 down here the first Elam that's likely to be synthesised is one 120 because even-numbered elements are more stable than odd-numbered elements and so it will be really interesting to

See whether one of these elements can be made soon periodic table is always waiting for new results in fact we already have a video about the possibility of element 120 which you can watch if you're interested

Chemistry is not finished this is just the beginning and I hope that 2016 is going to be really exciting year for chemistry and for science in general so again happy New Year to you all great success in your science and keep

Watching iodine in day Sarah do you know Asuma today CNN so ray Cara name a mo kurushimi nice name
