The GSI claim for element 112 has finally been accepted. Figured once they sorted out the issues with the decay products of ²⁷⁷112 (e.g ²⁶⁵Sg & ²⁶¹Rf, it was only a matter of time.  No proposed name has been submitted yet. Names based on GSI's location has already been used up (Hassium, Darmstadt). Most likely they will find another scientist to honor. Geiger is still available, but "geigerium" just doesn't come off the tongue well.

You know Dubna already has a list for when/if elements 113-116 and 118 get accepted. Flerovium is fairly obvious, IMHO. They tried to use Kurchatov already, but currently IUPAC policy is not to consider names if they have already been proposed and not accepted for elements in the past.

To get the IUPAC report go to http://iupac.org/publications/pac/ & click on "ASAP articles" under "RSS feeds". You can then download the report (no registration required) as a pdf file.
This report only covers element 112; claims for 113+ will be covered in a "subsequent report".
Germanium & europium have also already been used.

Not only does this report credit element 112 to GSI (a foregone conclusion since RIKEN confirmed the GSI work) but it also accepts the identification of ²⁸³112 in ⁴⁸Ca based reactions. That makes it almost certain that the discovery of 114 & 116 will also be accepted since the decay chains are now linked to an accepted nuclide.

[Dan1195]

I would think 113 would have to wait until Dubna's Element 115 chains can be verified. As RIKEN has tied 113 to known nuclides but only after 113 was observed by Dubna asa decay product.

The procedure to get this report has changed. Click on IUPAC Reports and Recommendations instead of ASAP articles. Otherwise it is the same.

named it finally too...

How is the last "c" supposed to be pronounced? like "eesium" or "ickium" I know the latter is how his name is pronounced but the former is like "Americium", which is also based off a name with a similar "c" ending.

[Dan1195]

Interesting to read in Popsci.com that they almost named it after Galileo. Interesting idea, but name would be a bit too close to Gallium for my taste, especially since we already have Bohrium which is similar to Boron.

Does the report not have a doi link, instead? Would http://dx.doi.org/10.1351/PAC-REP-08-03-05 always link to it?

The boys at GSI say that the name is with "eesium" in German (stressing the "s'), but that English speakers have to decide how they want it pronounced.  I have heard it both ways so far, but set my vote for "eesium".  IUPAC will not decide on the name/symbol for another few months.

[Dan1195]

One thing I just realized. Copericium is named for Copernicus, whose name means "one who works with Copper", IFAIK, this is the first time an element has been named for someone whose name refers to another element.

[Borek]

Good catch. His dad was involved in copper trade or smelting, hence the name.

It's official - copernicium, Cn. "Name and symbol of the element with atomic number 112 (IUPAC Recommendations 2010)" is now available at www.iupac.org/publications/pac/asap.
