Because he knew from his already discovered periods and groups of elements that the gaps would be filled by newly discovered elements.
If you have a gap such as this,
3d5__3d7
along a period's outer valance level you can predict, which Mendeleev did, that the element with the outer valance number,
3d6,
will be found in the future.

Why did Dmitri leave blank spaces on the periodic table?
Because those elements were not known at the time of Dmitri Mendeleev.
Who left spaces in the periodic table and why?
Dmitri Mendeleev
Which elements did Mendeleev leave space for in his first periodic table?
Mendeleev left spaces for undiscovered elements. He named them eka-aluminium, eka-silicon etc.
How did mendeleev explain blank spaces left in his periodic table?
On his Periodic Table Mendeleev left the blank spaces, because he thought there would be elements that would follow his pattern.
Why did Dmitri leave blank on the preodic table?
There is no specific reason mentioned for why Dmitri Mendeleev left blank spaces on the periodic table. It is believed that he left these spaces to accommodate elements that were yet to be discovered or to demonstrate the existence of elements with certain properties that were predicted but not yet confirmed. These blank spaces eventually led to the discovery of new elements and validated Mendeleev's periodic table.

Which elements did mendeleev leave spaces for in his periodic table?
Gallium, Silicon and Aluminum , -Peter
Why did Mendeleev leave three spaces on the periodic table?
Because those elements were not known when he formulated his periodic table.
How many blank spaces did Mendeleev leave in the periodic table which represented elements that had not yet been discovered?
Mendeleev left 3 blank spaces for the elements that had not yet been discovered.
Why did mendeleev leave blank spaces on his periodic table?
Mendeleev left blank spaces because certain elements on the Periodic Table were not known at that time. He knew that in the future, those elements would be found and placed on the periodic table.
Why did Dmitri leave blank spaces on the periodic table?
Because those elements were not known at the time of Dmitri Mendeleev.
Who left spaces in the periodic table and why?
Dmitri Mendeleev
How many blank spaces were in mendeleeves periodic table?
There were 3 blank spaces in mendeleev's Periodic Table. He left it for the elements which were not discovered at that time.
Which elements did Mendeleev leave space for in his first periodic table?
Mendeleev left spaces for undiscovered elements. He named them eka-aluminium, eka-silicon etc.
How did mendeleev explain blank spaces left in his periodic table?
On his Periodic Table Mendeleev left the blank spaces, because he thought there would be elements that would follow his pattern.
Why was Mendeleev's decision to leave blank spaces on his table sometime referred to as his most significant contribution to periodic table?
Mendeleev thought about the future and realized that it was entirely unlikely that all earthly elements had been discovered, so he left blank spaces in his table and even predicted some of the elements that would fit in those spaces. Surprisingly enough, as time passed, chemists began discovering many of the elements that he had predicted, which fit perfectly into his periodic table.
