Task: The elements 115, 117 and 118 would not have been discovered without the international collaboration of the research centres mentioned. Click on the link to watch the video and then read the following extract from the IUPAC website about the naming of these new elements:

Youtube Video on collaborative discovery

"The collaboration between the Joint Institute for Nuclear Research in Dubna, Russia; Lawrence Livermore National Laboratory, California, USA; and Oak Ridge National Laboratory, Oak Ridge, Tennessee, USA have fulfilled the criteria for element Z=115, 117 and will be invited to propose permanent names and symbols.

​The collaboration between the Joint Institute for Nuclear Research in Dubna, Russia and Lawrence Livermore National Laboratory, California, USA have fulfilled the criteria for element Z=118 and will be invited to propose a permanent name and symbol." (Koppenol, 2002)

Suggest a name and symbol for each new element in accordance to the IUPAC naming criteria below:

• "The proposed names and symbols will be checked by the Inorganic Chemistry Division of IUPAC for consistency, translatability into other languages, possible prior historic use for other cases, etc. New elements can be named after a mythological concept, a mineral, a place or country, a property or a scientist." (Koppenol, 2002)
• Historic use should be considered which means that the name should fit with similarly placed in the periodic table. E.g. Other large, radioactive elements end with -ium.
