Dmitri Mendeleev
Mendeleev explained the blank spaces in his periodic table by predicting the existence and properties of elements that had not yet been discovered. He organized the known elements based on their atomic weight and properties, which allowed him to accurately predict the properties of missing elements. These predictions helped guide the discovery of new elements that filled in the empty spaces in the table.
The gaps in the periodic table left by Mendeleev were eventually filled in as new elements were discovered. Scientists continued to study and experiment, leading to the discovery and verification of elements that fit into the empty spaces in the periodic 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.
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.
Metals are grouped together to the left of the 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.
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.

Because those elements were not known when he formulated his periodic table.

The periodic table is arranged from left to right in the order of atomic numbers.
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.
