The history of the periodic table's development is a culmination of contributions by various scientists, with Dmitri Mendeleev being the key figure in proposing the version we use today in the 1800s.
In 1869, both Julius Lothar Meyer and Dimitri Mendeleev independently proposed similar arrangements based on atomic mass and properties, leading to the modern periodic table. Mendeleev's table showed recurring trends in element properties and even predicted missing elements and their characteristics.
Chemists over time arranged elements based on reactivity and properties, with the periodic table evolving to align with electronic structure knowledge, aiding in predicting chemical behavior.
