Advantages And Disadvantages Of The Periodic Table

All of the inventions that are used by us nowadays are the results of the big works during the whole period. One of the most important things of the chemistry – Periodic Table – also has its own history. As we know, when some elements were identified and when their amount had increased, scientists needed some order to make them more comfortable to use and to understanding. To group them in the pattern were used relative for hydrogen atomic masses of the elements, known chemical and physical properties. In those times scientists couldn’t measure actual masses of elements, so they were measured against the mass of hydrogen. Scientists as Johann Döbereiner, Alexandre-Emile Béguyer de Chancourtois, John Newlands and Dmitri Mendeleev were the founders of the periodic table that we use today. Some scientists have added new discovered elements and complete the system that was founded by Mendeleev, as everyone found it as more convenient. It means that the table that

As we can see from the comparison of advantages and disadvantages of his table, it had given people more opportunities to develop. Also, this table could consider all of the trends that could be found and its disadvantages are solvable. By comparing with other periodic tables, we can be sure that all of them had reasons for being unused. For example, in Johann Döbereiner and John Newland’s tables most of the elements weren’t successfully placed, some of them even didn’t follow the trends that were noticed. Alexandre-Emile Béguyer de Chancourtois’s table wasn’t comfortable to use. So, Mendeleev’s table was the most completed and clearest, as it could satisfy all requirements of the scientists. Finally, Periodic Table was formulated by scientists of the world. Even they lived in different places and times, all of works that they had done is the whole system, as they improved each other’s
