The greatest triumph of Mendeleev's Periodic Table was his predictions of the existence of the undiscovered elements.
the prediction of the existence of undiscovered elements.
the periodic table of elements
Mendeleev's periodic table of elements certainly wasn't created in 1901
It looks the same as it did when Mendeleev created it. There are no changes made to the table throughout the years because Mendeleev had predicted the correct placement for all of our current known elements.
Dmitri Mendeleev was a Russian chemist who proposed the Periodic Law. He published the first periodic table of the chemical elements in 1869, based on the increasing atomic masses of the different elements.
He left gaps for the new elements. The properties could be estimated from the space left by him.
because they did not feel that his table was well enough to be used world wide.

To understand the concept of Periodic Table
Mendeleev's periodic table of elements certainly wasn't created in 1901
In Mendeleev's periodic table, the elements were arranged in the increasing order of their atomic masses and repeating periodic properties.
Mendeleev predicted that properties of elements are periodic function of atomic mass. He demonstrated it by creating a table.

In chemistry all most all elements properties are known based on periodic table.
