About
The periodic table of elements, created by Dmitri Mendeleev in 1869, organizes all known chemical elements by their atomic number and recurring chemical properties. Mendeleev's genius was leaving gaps for undiscovered elements and predicting their properties — three were confirmed within his lifetime. Today the table contains 118 confirmed elements.
The periodic table is one of science's greatest organizational achievements — it reveals the deep structure of matter and has guided the discovery of new elements, materials, and reactions for 150 years. Every element heavier than iron was forged in stellar explosions or colliding neutron stars — we are made of stardust.
