Whose periodic table arranged the elements by repeating properties?
ChemistryPeriodic Table
Quick Answer
Dmitri Mendeleev developed the first widely accepted periodic table in 1869. He arranged elements by recurring chemical properties and left gaps for undiscovered ones.
The Full Story
Dmitri Mendeleev is credited with creating the first widely accepted periodic table in 1869. He ordered the known elements largely by atomic weight and by recurring chemical behavior, which revealed a periodic pattern. Mendeleev famously left gaps for elements not yet discovered and predicted their properties with remarkable accuracy. His work became the foundation of the modern periodic table, later refined by atomic number rather than atomic weight.
