Seventh Line of Periodic Table is Completed – Indigo Ball – 15 Jan 2016 The day of 30 December 2015 has become highly memorable, as it has brought huge success in the field of science and technology. The scientists from Pure and Applied Chemistry (IUPAC) has announced that they have completed 7th row of period table through discovering four new elements. The periodic table shows the chemical elements in tabular form, arranged according to their atomic numbers, electron configurations and chemical properties. The table consists of both rows (periods) and columns (groups). The chemists have classified elements by the number of protons per atom (atomic numbers). On 30th December 2015, the scientists have announced that they have discovered all elements from atomic number 1 (hydrogen) to 118 (Ununoctium) through adding four new elements 113, 115, 117 and 118. The discovery of four new elements has completed the 7th line of period table. Unlikely to other elements, the newly discovered elements are human created and not natural through smashing heavy atoms with lighter atoms. The particle accelerators fired beams of lighter nuclei at samples of heavy elements, smashing the atoms together until of them fused. These four new elements have not yet given any name, because, the scientists who belong to Russia, Japan and America are likely to name them and symbolize them by their own. Temporarily, they have been given names as 113 (Ununtrium), 115 (Ununpentium), 117 (ununseptium) and 118 (Ununoctium). However, these names are expected to change in the future. The discovery of these four atoms has been known as biggest since 2011, when two elements 114 and 116 were added into a periodic table. The research work on these four elements was started in 2004. However, some experts say it has been started in 1999, when element 118 was discovered and the creation of 113, 115, 117 are the result of initial discovery. The impact of this new biggest discovery is expected to be very large, as it may lead to change rules and principles of science. Either this statement is true or not, the future will prove it, but overall, the discovery of new elements has opened doors of further research.
