According to a recent announcement, four new elements were added to the periodic table at the beginning of the year. The last time the periodic tables was updated was in 2011, scientists have explained.
2015 was a great year for science and you can tell this just by looking at the changes that are being made in 2016. The International Union of Pure and Applied Chemistry was proud to announced at the beginning of the week that four new elements were added to the periodic table to better illustrate the discoveries that have been registered lately.
The seventh row of the chart was left uncovered for decades, but this will change once the new elements will be included. The Union has added that the introduction of the new elements finally completes the seventh row.
Although the modification is set to trigger numerous changes in students’ books, scientists doubt that this will happen very soon. Their main goal for the moment is to find the right names for these four elements so they can add them to the chart.
So far, the heavy man-made chemical elements have been assigned three-figure codes that help distinguish them: 113, 115, 117 and 118. While these numbers may look like door numbers or postal codes to us, chemists know exactly what they stand for.
113 designates the ununtrium element, whose symbol is Uut. The chemical compound was identified by the Institute of Riken in Japan. Like in the name of most newly-identified elements, this compound, too, uses the name that the founder has chosen for it.
Similarly, elements 115 and 117 were named by their discoverers in Dubna, Russia and the United States, respectively. Their temporary names are ununpentium with the Uup symbol for number 115 and ununseptium or Uus for 117.
At number 118, scientists will soon add the chemical element of ununoctium, whose symbol is Uuo. The Union has further explained that this compound was first identified in Dubna and California.
The future names that these elements will take have to relate to their chemical properties, as well as to the places they are more common in. This way, it will be easier for students to understand what these heavy man-made elements can actually do.
This is the second update that the periodic table has seen in the past five years. The last time the period suffered modifications was in 2011, but the completion of the seventh row is not the last objective that researchers have set for themselves.
They will continue to investigate the properties of chemical elements and hopefully discover the 119th element. They plan to complete all the subsequent rows until they can finally get to an island of stability.
