Our history of the periodic table continues with the story of Dmitri Mendeleev. Visit: elementsunearthed.com to find out more. We interviewed Dr. Eric Scerri of UCLA, a leading authority on the history of the periodic table, and he discussed with us how Dmitri Mendeleev developed his periodic system in 1869 while working on a textbook of inorganic chemistry, and how he went on to publish the table and defend it, making bold predictions about missing elements and accommodating over 60 known elements by both atomic weight and chemical properties. His successors continued to revise the table, and the discoveries of subatomic physics and quantum mechanics finally explained the table's structure. Writing, narration, editing, photography, and animations were done by David V. Black.
