150 years ago, in 1869, D. I. Mendeleev and L. Meyer independently
published their ideas on the arrangement of the chemical elements in a
periodic system. The United Nations and UNESCO therefore declared 2019
the "International Year of the Periodic Table". The question arises,
what is so special about this "simple table"? Join the author on a short
journey to the history of the periodic table. Learn about its
predecessors and look at how the periodic table of elements has evolved
over the years. Discover the periodic properties of the elements. Learn
what makes the periodic table so interesting and timeless, and see what
other ideas there are and have been for representing it.
