Development of periodic table?
The modern periodic table of the elements was published by Dimitri Mendeleev in 1869. Several new elements have been discovered and added to the table since then.
What do the long dashes represent on mendeleev's periodic table?
Long dashes in the Mendellev's periodic table represent the element which were not discovered yet and these elements were discovered later on.
Why did Medellev leave gaps in the periodic table?
