The periodic table was first developed by [[Russia]]n [[chemistry|chemist]] [[Dimitri Mendeleev]]. Its layout accurately arranges elements by their [[electron]] configuration, atomic number, and chemical properties. Using the structure he created, Mendeleev predicted the existence and properties of several yet-undiscovered elements; when those elements were discovered, his estimates proved to be quite accurate.
