[Q] Names of elements 104-109?

[mats dahlgren]

Hello,

I know there has been decided on names for elements 104 - 109, which
are not Unnilquintuim, Unnilpentium, etc, and along with that there
are new chemical symbols different from Unq, Unp, Unh, Uns, Uno,
and Une. Does anyone have these names? Or a reference to where I
can find them?

thanks in advance,
mats d.

In 1993, the names below for 104, 105, 107-109 were officially adopted.
In 1994, the name below for 106 was adopted. IUPAC has recommended a
different set of names, but this recommendation awaits final
ratification and there is considerable agitation to keep them from
commiting an error in this regard.

104 Rf rutherfordium
105 Ha hahnium
106 Sg seaborgium
107 Ns nielsbohrium
108 Hs hassium
109 Mt meitnerium

For example, IUPAC wants to switch the name rutherfordium, which has
been used in much of the world for a quarter of a century, to element
106. They have also invented an after-the-fact ruling that an element
cannot be named after a living person despite that fact that this has
indeed occurred in the past. This nonsensical edict frees up seaborgium
to be renamed. However, IUPAC has authority to approve names, not to
impose them.

If IUPAC hasn't adopted these names, the who has, since they are
"officially adopted"??? I thought that official naming of elements was a
typical task for IUPAC and it's physics sister IUPAP.

It would be good to once and for all get names for those elements, since
the names for the first few elements of these have been under debate at
least since the seventies (?). I believe there was some east-west
priority struggle for one or several of these elements behind it. That's
probably why we got this sexless distilled-water-flavour "unniloctium"
and so forth naming system...

You can find the names in the following article:

International Union of Pure and Applied Chemistry.
Inorganic Chemistry Division.
Commission on Nomenclature of Inorganic Chemistry:
Names and symbols of transfermium elements : (IUPAC recommendations 1994)
In: Pure and applied chemistry. Vol. 66, no. 12 (Dec. 1994), p. 2419-2421

Or right here on the Internet:

104 Db Dubnium Dubna, near Moscow, where the Russian
nuclear research centre is situated
105 Jl Joliotium F Joliot-Curie, son-in-law of P&M Curie,
and Nobel laureate himself
106 Rf Rutherfordium E Rutherford (familiar to you, I hope)
107 Bh Bohrium N Bohr (idem dito)
108 Hn Hahnium O Hahn (nuclear fission)
109 Mt Meitnerium L Meitner (idem)

Element 109 doubles the number of 'female' elements to 2 ( the other
is 96, Curium :-) The names still await final approval from the
IUPAC Sanhedrin, scheduled to gather in August this year, however.

I found the follwoing names whichg are different form the listed above in some
WWW-Sites.
From Web-Elements I got

104 Rf Rutherfordium
105 Ha Hahnium

Form the Homepage of GSI (http://www.gsi.de), who made this isotops are these
names for the elements 107 to 109

107 Nb Nielsbohrium
108 Hs Hassium (latin, from the german federal state "Hessen")
109 Mt Meitnerium
