What did Dmitri Mendeleev develop?
Periodic Table of Chemical Elements
Periodic Table of Chemical Elements is correct.
The Russian chemist Dmitri Mendeleev published the Periodic Table of Chemical Elements in 1869.
He arranged the known elements in order of increasing atomic mass so that elements with similar properties fell in the same group, and he left gaps for undiscovered elements such as gallium and germanium, whose properties he predicted correctly.
Theory of Anarchy, Alpha Effect and The Golden Mean have no link with his work.
