Video with link.

Four new elements have been added to the periodic table, finally completing the table’s seventh row and rendering science textbooks around the world instantly out of date.

The elements, discovered by scientists in Japan, Russia and America, are the first to be added to the table since 2011, when elements 114 and 116 were added.

I can still remember that UFO game & Element-117... :D

nice to hear that those elements were found! ;)

Are these real natural elements, or artificially manufactured in a laboratory?

I think they are all artificial. 118 was made bombarding californium with calcium ions. It is not easy for a nucleus with many protons to be stable,given the electrostatic repulsion of the protons.

All of the new ones are created in a lab and are highly unstable.

Which is what I thought. In which case why is there so much fuss being made about it, when for all practical purposes they are simply ticks in boxes on a chart? In theory you could bombard every element with every other element and in time probably get another 1/2 dozen "new" ones, but what would be the point? This sounds like theoretical physics/chemistry purely for the sake of it. If the techniques used can be applied as a spin off for more practicable purposes like curing cancer, that might be different.

I am not decrying the technical achievement, just asking what benefits if any are likely to result from the work, apart from looking good on the CV.

I think they are looking for a "island of stability". Nuclear physics, not to be confused with elementary particle physics, is still being developed.

Uranium is the heaviest natural element that occurs in any quantity. There are trace amounts of plutonium that are present in uranium ore. Everything heavier than that is man made and has a very short life.

Uranium is atomic No.92. Are all these isotopes above that all artificial.

Just how many TRUE natural elements does the earth have?

There are some minute traces of Plutonium to be found in nature, in addition to the surface contamination from the atomic bombs that started in the 1940s.

About eight thousand kg of plutonium exist in nuclear warheads.

I think we should all sign this!

We believe it is fitting that the International Union of Pure and Applied Chemistry recommend that one of the four new discovered Heavy Metals in the Periodic table is named Lemmium.

I signed that one too! Thanks :)

Name new element 117 Octarine, in honour of Terry Pratchett's Discworld
I think we should all sign this!

But why element 117?
Octarine, also known as the Colour of Magic or the King Colour, was the eighth colour of the Discworld spectrum. It was visible only to wizards and cats.
I think element 118 should be called Octarine because it belongs to the noble gases.
For now it's this:
118 - Uuo - Ununoctium

I think because of the naming convention. It would be in group 7 of the periodic table so would be in the same group as chlorine and fluorine and bromine.

Of course it's the naming convention.
For now the new found elements are called one-one-(its atomic number - 110) in greek.
113 - Uut - Ununtrium
115 - Uup - Ununpentium
117 - Uus - Ununseptium
118 - Uuo - Ununoctium
It would be strange to qualify Octarine as Ununseptium instead of Ununoctium.

Septium means seven.
Octium means eight.

Two names to conjure with, especially when one considers how some earlier names were arrived at.....

Actually I think ES99 is probably right, there are pretty strict naming conventions on new elements often linked to their discovers as much as their groups. She teaches physics, so in this subject I accept she knows more than I do.

But naming one after a heavy metal band member is just childish and unacceptable.
