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.

There are currently no empty spaces on the Periodic Table. There will be when scientists discover Ununennium and begin the ninth period.
