Mendeleev predicted that properties of elements are periodic function of Atomic Mass. He demonstrated it by creating a table.

The usefulness of Mendeleev's periodic table was confirmed by the discovery of elements with predicted properties.
Because the properties of the elements change in a periodic fashion. In the early versions, when fewer elements were known, the chemically similar elements were thought to occur every eight positions.
The number of electrons an element has determine the organization. This table helps in making predictions about how an element will chemically react.

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.
If you mean his predictions about the periodic table then yes his predictions were correct.
they changed the 3 new Elements.

Dmitri Mendeleev was a Russian chemist; he proposed the modern Periodic Table of elements in 1869.
Periodic Principles Law of Periodicity Periodic Table of Toxic Elements These are three of the many discoveries Dmitri Mendeleev researched during his life (1834-1907).
The greatest triumph of Mendeleev's periodic table was his predictions of the existence of the undiscovered elements.
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.
