چکیده مقاله:

The discovery of the Periodic Table Elements by Mendeleev is one of the most significant achievements in science and a uniting scientific concept with extensive applications in various branches of science. The modern Periodic Table is the results of the efforts of many scientists, both chemists and physicists, before and after Mendeleev and one of the few scientific concepts that remained almost intact after 150 years. As the number of elements has gradually increased from 63 in the Mendeleev’s time to the present118, the discovered elements over the years have been easily located in their right expected places in the Table. The Periodic Table provides extensive valuable information about chemical and physical properties of the elements as well as the variations of these properties at the minimum time. Therefore, the Periodic Table is considered as one of the most efficient, updated and unique tool enabling scientists to predict the appearance and properties of matter on Earth and in the Universe. Its wide application is not limited to basic science but also extend to advanced research studies. The Periodic Table has an important role in developing the science dealing with atomic and molecular structure, because for each well-known periodic trend or the observed exception to that trend, an advanced scientific interpretation is required. Moreover, the Periodic Table, unlike some other scientific concepts, is unlikely becoming obsolete in the future but rather it is getting more and more importance in chemistry and other scientific disciplines. The discovery of element 118 in recent years has completed the 7th raw of the Periodic Table but whether the Table can be extended to higher atomic number super heavy elements or not still remained as interesting scientific challenge.
