<Tab/>The periodic table was an evolution in the history of chemistry. It aided scientists to predict elements that existed but not yet found. It helped people to interpret and understand the behavior and physical properties of various elements. The periodic table was developed and improved by scientists throughout the century as new discoveries were found. In the early eighteen hundred's, Dobereiner discovered that elements that are similar in appearance and …showed first 75 words of 443 total…

Rutherford assumed the alpha particles would go straight through before the discovery of the nucleus. In nineteen-forty, Glenn Seaborg discovered plutonium and all other transuranic elements. He reconfigured the periodic table by placing the actinide series below the anthanide series. He also won the noble prize in chemistry. The element "106" was named after him for the honor of his work.
