Addition of four new chemical elements to Mendeleev's table

ArabiaWeather.com - The International Union of Theoretical and Applied Chemistry announced the temporary addition of four new elements to the periodic table of chemistry, "Mendeleev's table".

The new elements that were added to the "Mendeleev table" in chemistry bear the atomic numbers: 113, 115, 117 and 118. The difficulty that scientists face in obtaining these new elements lies in the fact that they disintegrate into unknown isotopes of lighter chemical elements.

These new elements also bear temporary names, as follows: element 113 (ununpentium Uup), element 115 (ununpentium Uup), element 117 (ununseptium - Uus), and element 118 (ununoctium - Uuo). And the International Chemistry Union will give fixed names to these elements, to be included in Mendeleev's periodic table.
