Science gets its New Year gift in the form of four additional elements on the Periodic Table of Elements. The new additions not only complete periodic table's seventh row, but give high school chemistry students an opportunity to learn these superheavy chemical elements.

The International Union of Pure and Applied Chemistry (IUPAC) announced that the elements discovered by Japanese, US and Russian scientists will be known with their atomic number 113, 115, 117, and 118. They will soon be added to chemistry books with their permanent names, IUPAC said in a release.

Currently, the atomic number 113 has ununtrium’s temporary working name, while 115 is with ununpentium. Others atomic numbers (117 and 118) have ununseptium and ununoctium as their temporary working name. IUPAC said the scientists, who have discovered the elements, will propose permanent names to the atomic numbers.

“The chemistry community is eager to see its most cherished table finally being completed down to the seventh row. IUPAC has now initiated the process of formalizing names and symbols for these elements”, said president of IUPAC's Inorganic Chemistry Division, Jan Reedijk.

Before declaring these superheavy chemical elements, experts from the International Union of Pure and Applied Physics (IUPAP) and IUPAC outlined them in two reports. It may take some time to give permanent names to the elements as it’s a multi-tiered process. Once the scientists propose names, IUPAC’s Inorganic Chemistry Division will check them for consistency, history, and translatability into other languages. After finalizing two-letter symbols, they will be presented for five-month public review. After this exhaustive process, IUPAC will include the elements to the Periodic Table.

Scientists say the new elements are special as they cannot be found nature. The creators invented them by blasting beams of heavy nuclei at other nuclei inside particle accelerators.
