Addition of four new chemical elements to Mendeleev's table

<p style=";text-align:left;direction:ltr">ArabiaWeather.com - The International Union of Theoretical and Applied <strong>Chemistry</strong> announced the temporary addition of four new elements to the periodic table of chemistry, &quot;Mendeleev&#39;s table&quot;.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> The new elements that were added to the &quot;Mendeleev table&quot; 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.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> 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&#39;s periodic table.</p><p style=";text-align:left;direction:ltr"></p>
