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

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

The Green Table The Green Table is a ballet choreographed by Kurt Jooss. Jooss lived in Germany from 1901 to 1979 and choreographed the Green Table in 1932.

The connection between Sacks and the periodic table is explained by Sacks himself in his article “Oliver Sacks: My Periodic Table.” When first read‚ the connection is not obvious much like Picabia’s painting‚ but once we see beyond the text‚ the connection can be seen.

The Periodic Table The periodic table has been updated all throughout history. Elements have been around us since the beginning of time. Elements‚ such as gold and silver‚ are examples of these elements that have been known for centuries. The periodic table allows us to see the elements in their families so we can understand what properties they have. It also allows us to see the atomic number‚ atomic mass‚ and the symbol of the element. The periodic table is a source of knowledge that is still
