Atomic Mass Octaves and Triads
The 19th century.
Some people have suggested that Dmitri Mendeleev did first organize elements in a periodic table in a dream.
The periodic table was formed in the 19th century by Dmitri Mendeleev in 1869. Mendeleev organized the elements based on their properties and atomic weights, creating the foundation for the modern periodic table we use today.
Probable you think to the periodic table of Mendeleev.

Periodic Table of Elements.
Atomic Mass Octaves and Triads
The periodic table was set up in the 19th century, specifically in 1869 by Dmitri Mendeleev. Mendeleev organized the elements based on their properties and atomic weights, creating the foundation for the modern periodic table.

Dimitri Mendeleev
Atomic number was not used by Mendeleev to organize his periodic table. He organized the elements based on their atomic mass and properties, leaving gaps for undiscovered elements that were later filled.
he first organized his table in 1869 he did it by organizing them by atomic weights.
He organised the elements in the increasing order of the atomic mass.
