are there other representations of the periodic table
Alternative periodic tables Alternative periodic tables are tabulations of chemical elements differing significantly in their organization from the traditional depiction of the periodic system.[1][2] Several have been devised, often purely for didactic reasons, as not all correlations between the chemical elements are effectively captured by the standard periodic table.
History of the periodic table The history of the periodic table reflects over a century of growth in the understanding of chemical properties. The most important event in its history occurred in 1869, when the table was published by Dmitri Mendeleev,[2] who built upon earlier discoveries by scientists such as Antoine-Laurent de Lavoisier and John Newlands, but who is nevertheless generally given sole credit for its development.
