The Development of the Periodic Table: From Dalton to Mendeleev

The video explores the historical development of the periodic table, highlighting contributions from scientists like John Dalton, Newlands, and Dmitri Mendeleev. Initially, elements were organized by atomic weights, leading to some misplacements. Mendeleev's innovative approach included leaving gaps for undiscovered elements and reordering elements based on chemical properties, which was later validated by the discovery of atomic numbers.
