Why did Dmitri leave blank spaces on the periodic table?
Because those elements were not known at the time of Dmitri Mendeleev.
Why did mendeleev leave gaps in the table?
Scientists suggest Mendeleev left gaps in the periodic table because Mendeleev knew the elements existed; however, was unable to prove it.
When did the periodic table start getting used?
The periodic table of elements was first created by Dimitri Mendeleev in 1869. However, it took several years for his version to gain widespread acceptance and use. Since then, the periodic table has become an essential tool in chemistry and has undergone many revisions and refinements.
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.
How did mendeleev know that there were gaps in the the periodic table?
he knew that because of the new elements that were formed and he figured that the atoms would pop back and forth and leave gaps in between them.

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.
