Chemistry students (in fact, every school kid) must have read the Periodic Table.


Old Table

Students often have sleepless nights remembering the atomic number, name and symbols of the element from the tabular chart, which distributes the elements neatly into rows and columns.

So not-very-interested-in-chemistry students might find this as bad but the news is immensely exciting for the scientific community.

Until now, the seventh row of the table had four missing boxes because they were unnamed. But on December 30 the International Union of Pure and Applied Chemistry (IUPAC) confirmed the discovery of the missing four elements and announced they will be having names.

Till now they went by temporary working names and symbols.

And so we have elements 113, 115, 117 and 118 discovered and named fit for the new table, which will now look like this.



Periodic Table New

The discoverers of the elements are from Japan, Russia and US.

The Japanese team from RIKEN has been credited for the discovery of element 113, which goes by the temporary name and symbol of ununtrium and Uut, respectively.

Americans and Russians have been jointly credited for elements 115, 117 and 118 temporarily called ununpentium, Uup; ununseptium, Uus; and ununoctium, Uuo, respectively.


Element 113

Kosuke Morita of RIKEN reacts as he announces the news of the right to name element 113 on the periodic table.

The Joint Institute for Nuclear Research in Dubna, Russia collaborated with Lawrence Livermore National Laboratory, California, USA for the three elements.

Discoverers will get to name their discoveries and suggest the symbols. This marks a significant achievement for Asian researchers as element 113 will become the first to be named by them.

All four elements were created in laboratories and are extremely radioactive in nature. Element 113 was discovered in 2004; 115 in 2003; 117 in 2010; and 118 in 2006.
