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.

Dmitri Mendeleev left some vacant spaces in his Periodic Table because he predicted the existence of elements that had not yet been discovered. He used the properties of surrounding elements to predict the properties of these missing elements, which helped guide future research and 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.
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.
Who introduced the name periodic table?
It was named by Russian chemist Dmitri Mendeleev in 1869, in memory of his then recently-deceased colleague and clandestine "gentleman friend", Benjamin D. Periodic.
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?
K
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
Why did Dmitri leave blank spaces on the periodic table?
Because those elements were not known at the time of Dmitri Mendeleev.
Who inven ted the periodic table of elements?
several attempts were made before him, but nearly all books give credit to Dimetri Mendleev.

Why is Mendeleev called the father of the modern periodic table and not Meyer or both?
The two tables were virtually identical. However, because he drafted his table earlier in 1869 and because his table included "blanks" for yet-to-be-discovered elements to fit, Mendeleev is given the major recognition for the organization of the elements.
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 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.
