Dimitri Mendeleev, 1869.
It was recognized by the inventor of the Periodic table that these empty spaces are for elements/isotopes that would be discovered someday. Dmitri Mendeleev is generally credited with the publication, in 1869, of the first widely recognized periodic table. He developed his table to illustrate periodic trends in the properties of the then-known elements. Mendeleev also predicted some properties of then-unknown elements that would be expected to fill gaps in this table.

Rock is not an element and therefore is not on the periodic table. Only elements are on the periodic table

I suppose that you think to chemical elements, not to compounds. Dimitri Mendeleev is credited for the creation of the periodic table of elements.
Dmitri Mendeleev is credited with the publication of the first widely recognized periodic table.
Dmitri Mendeleev and Julius Lothar Meyer independently published there versions of the Periodic Table between 1869 and 1870. Mendeleev's version would become the foundation of the table used today.
Dmitri Mendeleev made the periodic table. He is credited as being the creator of the first version of the periodic table of elements. Using the table, he predicted the properties of elements yet to be discovered.
He is credited for creating the periodic table.
Niels Bohr
Periodic table is generally credited to Russian chemist Dmitri Mendeleev.
The modern long form of periodic table was constructed by Dmitri Mendeleev (1869).
