Meet the 4 NEW ELEMENTS of the Periodic Table

Four new elements have been added to the periodic table, finally completing the table’s seventh row and rendering science textbooks around the world instantly out of date.

Elements 113, 115, 117 and 118 have formally been recognized by the International Union of Pure and Applied Chemistry (IUPAC), the U.S.-based world authority that governs chemical nomenclature, terminology and measurement, which announced it on December 30.

They are the first to be added to the table since 2011, when elements 114  (Flerovium) and 116 (Livermorium) were added. Devised by Russian chemist Dmitri Mendeleev in 1869, the Periodic Table categorizes chemical elements according to their atomic number.

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).

A Russian-American team at the Joint Institute for Nuclear Research in Dubna, and Lawrence Livermore National Laboratory in California discovered elements 115, 117 and 118, while Japanese researchers were credited for discovering Element 113.

All four elements are not found in nature, and were synthetically created in laboratories, and were were discovered by slamming lighter ­nuclei into each other and tracking the following decay of the radioactive superheavy elements.
Until now, these elements had temporary names and symbols on the periodic table as their existence was hard to prove. Since they decay extremely quickly, scientists found it difficult to reproduce them more than once
With the discovery process now over, researchers have to come up with permanent names and symbols for the new elements, which may be named after a mythological concept, a mineral, a place or country, a property or a scientist.
