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 else can I help you with?
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?

Why was the discovery of germanium important for Mendeleev's table?
The discovery of germanium was important for Mendeleev's periodic table because its properties matched the gaps he had predicted in his table. This provided evidence for the periodicity of elements and the accuracy of Mendeleev's arrangement. Germanium's discovery also helped validate the periodic law which states that the properties of elements are periodic functions of their atomic numbers.
Did Mendeleev think all the elements had been discovered?
No, Dmitri Mendeleev did not believe that all the elements had been discovered when he created his periodic table in 1869. He left gaps in his table for elements that were yet to be discovered, predicting their properties based on the patterns he observed. Mendeleev's foresight proved accurate when several of these missing elements, such as gallium and germanium, were later identified.

He was Russian
Who is mendeleev and Meyer?
Dmitri Mendeleev and Julius Lothar Meyer were two chemists who independently developed early versions of the periodic table of elements in the 1860s. Mendeleev is often credited with creating the first widely recognized periodic table, organizing elements by their atomic mass and predicting the properties of undiscovered elements. Meyer also arranged elements based on atomic volume and demonstrated periodic relationships, but Mendeleev's table included predictions that later proved accurate, solidifying his legacy in the field of chemistry. Both contributions were crucial in understanding the organization of elements in chemistry.
The atomic theory was supported by mendeleev when scientist did what?
The atomic theory was supported by Mendeleev when scientists discovered that elements displayed a periodic trend in their properties when arranged by increasing atomic weight. Mendeleev used this information to create the periodic table, organizing elements by their atomic weights and predicting the properties of missing elements.
When was the magic bullet invented?
Paul Elrich was proved right in 1909.
Which elements proved difficult for mendeleev to add to his table because they were found to combine in various ratios with other elements?
The noble gases, such as helium, neon, and argon, were difficult for Mendeleev to add to his table as they were found to be chemically inert and did not easily combine with other elements in fixed ratios. This challenged the periodicity of his table, which was based on the repeating patterns of chemical properties.
