Simple. Dmitri left blanks because he predicted and knew that more elements of which he was unaware had to exist, and that they would most likely be discovered soon. He could make this assumption based on his calculations. According to his table and his research, he surmised that elements similar to the ones he already knew had to exist, and where they would be on his table. One of the most striking features of periodic organization is this ability to predict based on previous information.

How long did it take Mendleev to organize the periodic table?
it took mendleev FROM 1872 TO 1871. He figured it out in a dream that he had had whilst trying to figure out the problem
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.
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 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.
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.
