Four new elements have just been added to the periodic table
The periodic table, which groups the chemical elements according to their chemical composition and properties, just got four new elements added to it, thus completing its seventh row.
The new elements – 113, 115, 117 and 118 – were discovered by scientists from Japan, Russia and the United States and confirmed by officials from the International Union of Pure and Applied Chemistry (IUPAC). These are the first elements to be added to the table since 2011, when elements ۱۱۴ and 116 were added. The table was first created in 1869 by Russian scientist Dmitri Mendeleyev.
According to The Guardian, IUPAC announced that a team of US and Russian researchers at the Joint Institute for Nuclear Research in Dubna and Lawrence Livermore National Laboratory in California had produced sufficient evidence to claim the discovery of elements 115, 117 and 118.
