Why did Dmitri leave blank spaces on the periodic table?
Because those elements were not known at the time of Dmitri Mendeleev.
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.
How did Mendeleev predict the existence of unnatural elements?
He left blank spaces in the periodic table in the correct grouping and period that is where the newly discovered elements were placed.
How did Mendeleev know where to leave the spaces in his periodic table?
mandeleev didn't know spaces in the Periodic Table because he doesn't arrange it john Kepler arrange it most of mendeleev discoveries of elements are few most of other element where discover by other scientist after him in 19th century
What did Mendeleev do that was so important?
He created a periodic table arranged by atomic mass. He wasn't the first, but he was the first to leave spaces in his table for unknown elements. At his time, there were only 63 known elements. Based on the elements around the blank space, scientists could predict the properties of the unknown element. The spaces were filled in when they were discovered.
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.
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 did Dmitri leave blank spaces on the periodic table?
Because those elements were not known at the time of Dmitri Mendeleev.
What were the names of three elements Dmitri Mendeleev predicted from the blank spaces that Dmitri Mendeleev on the periodic table?
http://en.wikipedia.org/wiki/Mendeleev%27s_predicted_elements It says he predicted more than three.

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.
What was Mendeleev's contribution to the knowledge of elements?
When making his periodic table Mendeleev noticed some spaces where elements should be couldn't be filled. He didn't want to force elements that didn't belong there to go there, so he believed the spaces were undiscovered elements. He left the names blank but predicted their properties. Later the elements Mendeleev predicted existed were discovered.
What was the thing that was blank on Mendeleev's periodic table?
The elements which were not discovered at that time were made blank. Mendeleev named them as eka-aluminium, eka-silicon etc. They were discovered later and were placed in the gaps.
Why did Mendeleev leave blanks in his early version of the periodic table?
At the time the periodic table was first devised, there were many elements that had not yet been discovered. Their existence could be inferred, but they couldn't actually be put into the table until they were discovered.When the periodic table was first devised, there were lots of elements that had not been discovered yet.
What are the periods in Mendeleev's periodic table?
Because some of the elements were not yet discovered so he left them blank for other elements to be discovered. -bobby corner
