HISTORY OF THE PERIODIC TABLE How did the periodic table develop? Since a very long time‚ elements such as gold‚ silver‚ tin‚ copper‚ lead and mercury have been known.

Development of the periodic table ➢ The elements in the periodic table have been arranged in the order of the number of protons (a.k.a. atomic number) The next significant stage in the development of the periodic table was discovered by came from John Newlands. He arranged the known elements in order of their atomic masses. He introduced the ‘law of octaves’ which meant that every eighth element had similar properties. As it didn’t work for all the known elements it was therefore dismissed

I believe the periodic table will continue to evolve as new elements are discovered. One of the earliest attempts to organize the elements based on their chemical and physical properties was made by German

The Periodic Table is a chart which arranges the chemical elements in a useful‚ logical manner. Elements are listed in order of increasing atomic number‚ lined up so that elements which exhibit similar properties are arranged in the same row or column as each other. Elements are also arranged in different families and periods based on similar characteristics. Also the grouping of elements into into subcategories Metals‚ Nonmetals‚ and Metalloids. The Periodic Table is one of the most useful tools
