ScienceChemistry
Quick Answer
Dmitri Mendeleev created the first widely accepted periodic table in 1869. He arranged the elements by atomic weight and predicted missing ones.
The Full Story
Dmitri Mendeleev is best known for creating the periodic table in 1869. He organized the then-known elements by repeating chemical properties and atomic weight, leaving gaps where he believed undiscovered elements belonged. His predictions for elements such as gallium and germanium were later confirmed, which strongly validated his system. The modern table now uses atomic number, but Mendeleev's structure remains the basis of chemical organization.
