Four new periodic table elements get their names

The naming of new elements on the periodic table is subject to a lot of
discussion and comment involving a vast range of constraints, and a
committee solely dedicated to the process. Despite the difficulty and
length of the process, four new elements now have proper names that
honor the places and people essential to their discovery. 
Charged with deciding the labels for the newly discovered elements
with the atomic numbers, 113, 115, 117, and 118 (previously known as
ununtrium, ununpentium, ununseptium, and ununoctium, respectively) was
the US-based Inorganic Chemistry Division of the International Union of
Pure and Applied Chemistry (IUPAC) who, after a considerable
consultative process (completed on December 30, 2015), have now launched
a list of names to be subject to a final five-month public review. 
And if you think floating names to your
relatives is tough, just be glad you don’t have complications inherent
in naming new elements. Conventions dictate that new elements can be
named after a mythological concept or character (including an
astronomical object); a mineral or similar substance; a place, or
geographical region; a property of the element; or a scientist.
Added to this, the ending of names must also adhere to guidelines
around historical and chemical consistency, so that “-ium” ends names of
elements that are part of groups 1-16, on the periodic table, while
those finishing with “-ine” are specified for elements of group 17, and
the “-on” suffix represents elements in group 18. To top it all off, the
labels in English must also allow for correct translation into other
prime languages.
Now that this exhaustive collection of
conditions have been met, the proposed new names are nihonium, with the
symbol Nh, for element 113; moscovium, with the symbol Mc, for element
115; tennessine, given the symbol Ts, for the element 117; and
oganesson, with the symbol Og, for element 118.
The first three elements are named for their
places of discovery, and the last is named for a scientist affiliated
with the area of study the element is associated with – Professor Yuri
Oganessian, renowned for his groundbreaking research into transactinoid
elements. Such elements are those that are the artificially produced
radioactive elements with the atomic numbers 104 to 121. 
As for the other atomic elements, nihonium
with the symbol Nh and number 113 on the periodic table has been named
for its Japanese discoverers who created it in a particle accelerator by
bombarding bismuth with zinc ions traveling at about one-tenth the
speed of light. Element 113 is the first to have been discovered in an
Asian country and Nihon is one of the two ways to say “Japan” in
The next two names are fairly
self-explanatory with moscovium (element 115, symbol Mc) honoring
Moscow, and tennessine (117, symbol Ts) representing the US state of
Tennessee. These names were proposed jointly by scientists at the Joint
Institute for Nuclear Research, Dubna (Russia), Oak Ridge National
Laboratory (USA), Vanderbilt University (USA) and Lawrence Livermore
National Laboratory (USA), who worked together to find the new elements.
