Interactive Periodic Table The periodic table was created by Professor Dmitri Mendeleev in 1869 using the properties of known elements. The Periodic Table organises the elements so that elements with similar properties are in the same column ('Group'), with elements across a row ('Period') shown in order of increasing atomic number. So the Periodic Table links the stucture of the atoms of an element with its properties. Many other interactive periodic tables are available on the web; you can learn more about elements in the Periodic Table in the Visual Elements table from the Royal Society of Chemistry and this photographic one.
