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.
What else can I help you with?
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.
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 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.
How long did it take Mendleev to organize the periodic table?
Dmitri Mendeleev developed the periodic table over a period of around 6-7 years from 1869 to 1875. He arranged the elements based on their atomic mass and chemical properties, leaving gaps for undiscovered elements which he predicted would exist.
Why did Dmitri Mendeleev leave some squares in his table blank?
Mendeleev left blank spaces in his periodic table to account for elements that had not yet been discovered. He predicted the properties of these missing elements based on the patterns he observed in the table. This empty spaces allowed for the periodic table to be a predictive tool for the discovery of new elements.
Who thought about the periodic table before Dmitri mendleev?
Lothar Meyer thought about the periodic table before Dmitri mendleev. However, his work was not published until after the work of Mendleev.
Who discovered periodic table organized by atomic mass?
mendleev
Why mendleev made a new periodic table?
He didn't, his was the first and last
Why did Dmitri Mendeleev leave spaces in the periodic table?
Because
Why did Mendeleev leave three spaces on the periodic table?
Because those elements were not known when he formulated his periodic table.
Which elements did mendeleev leave spaces for in his periodic table?
Gallium, Silicon and Aluminum , -Peter
Who inven ted the periodic table of elements?
several attempts were made before him, but nearly all books give credit to Dimetri Mendleev.

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.
Why was leaving spaces and gaps in the periodic table later vindicated?
Leaving spaces and gaps in the periodic table allowed for prediction of new elements and their properties, which were later discovered and filled in. This vindicated the decision to leave gaps, as it demonstrated the power of the periodic table in organizing and predicting the properties of elements.
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.
