Going through a long journey filled with success, failures, and discoveries, finally the periodic table is complete. Scientists have confirmed the discovery of four new elements which has completed the table, filling the empty spaces. Elements with atomic numbers 113, 115, 117, and 118 have been discovered.

The discoveries were made in Japan, Russia, and United States. The Japanese research team discovered the element “113”. Reportedly, the team has got the permission to name the element. This will be the first element in the periodic table to be named after an Asian scientist.

115 was discovered about a decade ago by Russian scientists but recently Swedish scientists replicated the experiments and synthesized the same element again. After getting confirmation from IUPAC, the element has been added to the periodic table. A heavy unstable element, “Americium” was bombarded with calcium atoms for days and weeks. Some of these atoms bounced back but still some stuck to the Americium atom giving rise to a nucleus with 115 protons.

NAMES AND SYMBOLS OF NEWLY DISCOVERED ELEMENTS

ATOMIC NUMBER                      NAME                          SYMBOL

113                                       NIHONIUM                       Nh

115                                       MOSCOVIUM                    Mc

117                                       TENNESSINE                    Ts

118                                       OGANESSON                    Og

Claims of the discovery of element 118 were not entertained back in 2002, however recently another group of researchers have claimed the discovery of the same element again.

With these discoveries, the periodic table seems to be complete.
