 Hi team - We haven't finished the last element for our Element Quiz but I
just found this information and thought it would be a good Thursday
diversion.

Naming of Elements 113, 115, 117, 118 Has Been Announced:

The most recent paper covering the element naming guidelines is available
since early 2016 [22], and its main points are summarized here. In keeping
with
tradition, newly discovered elements can be named after:
(a) a mythological concept or character (including an astronomical object),
(b) a mineral, or similar substance,
(c) a place, or geographical region,
(d) a property of the element, or
(e) a scientist.

To avoid confusion in the literature, when a name has been used for a
particular element, but a different name is ultimately chosen for that
element, then
the first name cannot be transferred for use for another element. The names
of all
new elements in general would have an ending that reflects and maintains
historical
and chemical consistency. This would be in general “-ium” for elements
belonging to
groups 1-16, “-ine” for elements of group 17 and “-on” for elements of
group 18. Finally
the names for new chemical elements in English, should allow proper
translation
into other major languages.

Following the assignment and in accordance with the procedures established
by IUPAC for the naming of elements [22], the discoverers at RIKEN Nishina
Center
for Accelerator-Based Science (Japan), Joint Institute for Nuclear
Research, Dubna
(Russia), Oak Ridge National Laboratory (USA) and Lawrence Livermore
National
Laboratory (USA) were invited by IUPAC to propose names and symbols for the
elements with atomic numbers 113 (RIKEN), 115, 117 (Dubna, Livermore, Oak
Ridge) and 118 (Dubna and Livermore). The outcomes of this process are as
follows:

*Element 113*
The name nihonium and symbol Nh are proposed for element 113. Nihon is
one of the two ways to say “Japan” in Japanese, and the name is proposed to
make
a direct connection to the nation where it was discovered, and also to
celebrate the fact that it is the very first element in the history of the
periodic table to be discovered
in, and to be named after, an Asian country.

NB: The discoverers respectfully note the 1909, never sustained, claim and
proposal by Masataka Ogawa for nipponium as element 43 [23, 24] and the
name is
also a homage to his work.


*Element 115*
It is proposed that the name moscovium and symbol Mc are given to
element 115. Moscovium is recommended in recognition of the Moscow region
and
honoring the ancient Russian land that is home to the Joint Institute for
Nuclear
Research, where the discovery experiments were conducted using the Dubna
Gas-Filled Recoil Separator in combination with the heavy-ion accelerator
capabilities of the Flerov Laboratory of Nuclear Reactions, JINR.


*Element 117*
The name tennessine and symbol Ts are proposed for element 117.
Tennessine is recommended in recognition of the contribution of the
Tennessee
region, including Oak Ridge National Laboratory, Vanderbilt University, and
the
University of Tennessee at Knoxville, to superheavy element research,
including the
production and chemical separation of unique actinide target materials for
superheavy element synthesis. Actinoid materials from Oak Ridge have
contributed
to the discovery and/or confirmation of nine superheavy elements.
NB: We are aware of the fact that Ts is often used as abbreviation for the
tosyl chemical group. However, this was not considered to be a valid
objection,
given the fact that we also use the symbols Ac and Pr for chemical
elements, while
chemists also use these as abbreviations for the acyl and the propyl
groups. Very
common items like AcOH and PrOH are usually not taken for the hydroxides of
actinium and praseodymium and a possible confusion with the tosyl group seem
extremely low. On the other hand, the abbreviation Tn, that might have been
a
natural suggestion, is impossible given the earlier (1923) CIAAW-IUPAC
acceptance of that symbol for thoron (220Rn), and its regular usage since
then, see
e.g. Journal of Environmental Radioactivity.

*Element 118*
The collaborating teams have proposed oganesson and symbol Og for
element 118. Oganesson is proposed in recognition of Prof. Yuri Oganessian
(1933-) for his pioneering contributions to transactinoid elements
research. His
many achievements include the discovery of superheavy elements and
significant
advances in the nuclear physics of superheavy nuclei including experimental
evidence for the “island of stability”.
NB: This is the second time an element has been named after a living person,
the first being element 106, seaborgium in 1997 [25], after transuranium
pioneer
Glenn T Seaborg (1912-1999).
