On 30th December 2015, International Union of Pure and Applied Chemistry (IUPAC) officials verified the discovery of four latest super-heavy elements which have been added to the periodic table recently, completing the table’s seventh row.
The elements 113, 115, 117, and 118, discovered by scientists from Japan, Russia and USA, are the first to be added to the table since year 2011, when elements 114 and 116 were added to the periodic table.
“The chemistry community is eager to see its most cherished table finally being completed down to the seventh row,” President of the Inorganic Chemistry Division of IUPAC,Professor Jan Reedijk.
“IUPAC has now initiated the process of formalizing names and symbols for these elements temporarily named as ununtrium, (Uut or element 113), ununpentium (Uup, element 115), ununseptium (Uus, element 117), and ununoctium (Uuo, element 118).”
Kosuke Morita, who was leading the research at Riken institute in Japan, told his team is now planning for other notable elements.
“look to the uncharted territory of element 119 and beyond.”
Former Riken president and Nobel laureate in chemistry, Ryoji Noyori, said:
“To scientists, this is of greater value than an Olympic gold medal”
The newly discovered elements will be officially named by the teams that discovered them in the upcoming months.
Moreover, Element 113 will be the first element to be named in Asia.
Reportedly, the new elements can be named after a place or country, mythological concept, a mineral or after the property or scientist.
The four new man-made elements, were discovered by slamming lighter nuclei into one another and tracking the following decay of the radioactive super-heavy elements.
The new elements can only exist for fractions of second before decaying into other elements just like every other super-heavy elements that populate the end of the periodic table.
