Why aren't there any j's on the periodic table of elements?

But first, I found some info at http://www.webelements.com regarding Bohrium/Nielsbohrium:

The German discoverers at GSI proposed the name Nielsbohrium (symbol Ns) after Niels Bohr. IUPAC are happy to name an element after Bohr but suggest bohrium (Bh) on the grounds that the first name of a person does not appear in the names of any other element named after

The site also indicates that the confusion for the names of elements 104-108 is apparently due to the International Union of Pure and Applied Chemistry (the organization that ultimately approves the offical names) and the American Chemical Society disagreeing on appropriate names in the mid 90s. This controversy has been resolved.

Here is a list of the old IUPAC names, old ACS names and final offical names (in bold):

104 - Dubnium, Rutherfordium, Rutherfordium
105 - Joliotium, Hahnium, Dubnium
106 - Rutherfordium, Seaborgium, Seaborgium
107 - Bohrium, Nielsbohrium, Bohrium
108 - Hahnium, Hassium, Hassium

Meitnerium has never been in dispute.

So it looks like we almost had a Jl on the periodic table, José.

No names have been suggested yet for the recently discovered elements 110-112. Maybe J.J. from “Good Times” will finally get an element named after him.

I didn’t know about Meitnerium. As far as I know, it’s the only element named after a woman (Lise Meitner). Curium was named after both Marie and Pierre Curie. If there ever is a Joliotium, it will probably honor both Frédéric and Irène Joliot-Curie.
