About : The development of the periodic table is the discovery of elements and effects on science. Some of the elements known to the ancient man are gold, silver, copper, iron, lead, tin, mercury sulfur and carbon. Meanwhile, arsenic, antimony, phosphorous and zinc were also discovered. One of the earliest attempts to organize the elements was by Johann Dobereiner. He organized elements into three or triads based on similar qualities. English chemist John Newland discovered the first table of elements. The name of the group is "laws of octaves". So on this day, people try to observe the worth and importance of the periodic table.
