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.

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.
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 did Dmitri leave blank spaces on the periodic table?
Dmitri Mendeleev left blank spaces on the periodic table to account for elements that had not been discovered yet. He predicted the existence and properties of these missing elements based on the patterns and trends of the known elements in the table. This allowed for the successful prediction of the characteristics of elements like gallium and germanium.
Mendeleev arrange the known chemical elements in a table according toincreasing?
Mendeleev arranged the known chemical elements in a table according to increasing atomic mass and similar chemical properties. This arrangement led to the periodic table of elements, where elements with similar properties fall into the same column or group. This organization allowed Mendeleev to predict the properties of undiscovered elements and leave spaces for them in the table.
Why did Mendeleev leave a space for the unknown at the time element germanium in his periodic table?
Because germanium was not known at the time when Mendeleev formulated his periodic table.
Why did Dmitri Mendeleev leave spaces in the periodic table?
Because
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 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.
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.
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 many blank spaces did Mendeleev leave in the periodic table which represented elements that had not yet been discovered?
Mendeleev left gaps for eight elements in his periodic table that were yet to be discovered. These gaps eventually corresponded to the elements gallium, germanium, scandium, technetium, francium, and technetium.
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.
Why was Mendeleev's decision to leave blank spaces on his table sometime referred to as his most significant contribution to periodic table?
Mendeleev's decision to leave blank spaces on his table accurately predicted the existence and properties of undiscovered elements, demonstrating the periodicity of the elements. This foresight laid the foundation for the discovery of elements such as gallium, germanium, and scandium, validating his periodic table and contributing significantly to the organization of elements.
