Was Mendeleev's periodic table accurate enough that he was able to use it to predict the existence and several properties of certain elements that had not yet been discovered?
Mendeleev was able to predict the properties of the elements that were not discovered at that time. He left gaps for these elements in his Periodic Table.
How has the table changed over time?
New elements have been discovered or synthesized and added to the Periodic Table.
How was Mendeleev's periodic table validated?
The confirmation is that new elements discovered have been correctly inserted in table.
