The validity of the Periodic Table of elements, which was originally devised by Mendeleev, has been confirmed by a vast body of chemical research. It would not be an exaggeration to say that everything in the science of chemistry conforms to Mendeleev's theory.

What was the importance of Rutherford's experimental results and predictions being the same?
it proved that his idea was potentially right
Why are tentative theories?
Those are theories that are possibly right, but not proved correct yet.
What group of elements did Mendeleev omit?
i have no idea but i will check and keep you posted.
How many books did Dmitri mendeleev write?
Dmitri Mendeleev only wrote many books, somewhere around the number of 250 publications. His most famous work is the book "Organic Chemistry" that was published when Mendeleev was 27 years old.
What did mendeleev use to find the elements with?
i need help
Why was the discovery of germanium important for Mendeleev's table?
Because he manged to predict it being there so he was proved right and proved a genius!
Which elements proved difficult for mendeleev to add to his table because they were found to combine in various ratios with other elements?
Copper and magnesium are elements that were difficult for Mendeleev to add to his table because they were found to combine in various ratios with other elements.copper and manganese
Who proved Vespucci right?
Balboa
The atomic theory was supported by mendeleev when scientist did what?
The atomic theory that was supported by Mendeleev when scientist found the elements that Mendeleev predicted was out there in the world. When Mendeleev made the periodic table he left spots for elements he did not have but knew would be found one day.
