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periodic table, finally completing the table’s seventh row and rendering science textbooks around the world instantly out of date.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 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.

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.

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.

Name new element 117 Octarine, in honour of Terry Pratchett's Discworld

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 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.....

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

Yes, you are right Chris.
Skandium and Ytterbium should also be renamed.
Totally unacceptable to have those childish names!

In 1878, the Swiss chemist Jean Charles Galissard de Marignac separated in the rare earth "erbia" another independent component, which he called "ytterbia", for Ytterby, the village in Sweden near where he found the new component of erbium.

Scandium is a chemical element with symbol Sc and atomic number 21. A silvery-white metallic d-block element, it has historically been sometimes classified as a rare earth element, together with yttrium and the lanthanoids. It was discovered in 1879 by spectral analysis of the minerals euxenite and gadolinite from Scandinavia.

Here is the total list of childish names for elements found in a small Scandinavian quarry!
Yttrium (of Ytterby)
Ytterbium (of Ytterby)
Terbium (of Ytterby)
Erbium (of Ytterby)
Holmium (of Holmia, the Latin name for Stockholm)
Scandium (Scandinavia)
Thulium (Thule, the Latin name of Scandinavia)
Gadolinium (after Johan Gadolin)
Tantalum (after the Greek mythological character Tantalus)

Lemmium petition update:)

‘Don’t usually support campaigns but this one must surely be right’ – Professor Brian Cox.
Before his academic career, Cox was a keyboard player for the bands D:Ream and Dare.
https://en.wikipedia.org/wiki/Brian_Cox_(physicist)

Anyway.
Lemmy himself said in 2010:
"We were not heavy metal," he snaps. "We were a rock'n'roll band. Still are. Everyone always describes us as heavy metal even when I tell them otherwise. Why won't people listen?"

I guess we have to find something else to name the new heavy metals.

Hmmm. Ledzeppelinium:)
