What is the chemical symbol for Ununpentium

Ununtrium, Ununpentium, Ununseptium and Ununoctium : Discovered four new chemical elements

The periodic table of the elements, the icon of all chemists, just got a little more beautiful. The International Union of Pure and Applied Chemistry (IUPAC) has officially recognized four new elements. With that, the seventh row of the periodic table is finally complete. The only question is, which is easier: to make the elements or to pronounce their names.

One of the elements could be called "Japonium"

Ununtrium, Ununpentium, Ununseptium and Ununoctium (stands for the ordinal numbers 113, 115, 117 and 118) - that hardly crosses your lips, let alone is it even remotely beautiful or inspiring like xenon, indium or zirconium. Fortunately, the cumbersome names are only working titles; the researchers involved in the discovery are now asked to find catchy names and associated symbols, each made up of two letters.

According to the specifications of the IUPAC, the elements can be named after a city, a country or a researcher, names from a mythology are also possible. It is crucial that the name is reasonably consistent with the other names and can be easily translated into other languages. For element 113, for example, which was first discovered in Japan twelve years ago, the suggestion “Japonium” was circulating at the time. It is quite possible that this will happen, because the Japanese research team from the Riken Center has now been granted the right to propose. For the rest of the newcomers to the periodic table, priority has been given to Russian and US scientists from the Dubna Nuclear Research Center, Lawrence Livermore, and Oak Ridge National Laboratory.

Beyond element 120, there should hardly be anything to be found

You've all done a lot of hard work and been lucky enough too. Because the "super-heavy" elements do not occur in nature and only arise for fractions of a second in particle accelerators when two atomic nuclei fuse together - they immediately decay again into lighter elements. Sometimes years pass before a few of the short-lived atoms can be detected.

Scientists have long been chasing elements 119 and 120. According to experts, even heavier ones are unlikely to be produced.
