The usefulness of Mendeleev's periodic table was comfirmed by?
The usefulness of Mendeleev's periodic table was confirmed by the discovery of elements with predicted properties.
Why did Dimitri Mendeleev predict that more elements with specific properties would be discovered?
because,he predicted some possible chemical formulas of the then undiscovered elements between the elements in his periodic table. so he concluded that more elements with specific properties would be discovered.
What problems did the Periodic Table solve?
The table helped explain why chemical transmutation was not possible, thus answering age old questions of alchemy. It beautifully organized the known elements, and predicted properties of undiscovered elements.
What are the advantages of Mendeleev periodic table?
- predicted the discovery of undiscovered elements and also predicted their properties. - highlighted some atomic weights of elements were incorrect - showed regular gradartion in physical and chemical properties of elements. - provided for variance from atomic weight order - provided the basis for the modern periodic table
How did Dmitri Menedeleyev arrange elements on his first periodic table?
Mendeleev arranged the elements in a table with the rows ordered by atomic mass and the columns ordered the elements properties.
How was Menndeleyev able to predict the existence of elements that had not yet been discovered?
Mendeleev left gaps for undiscovered elements. He predicted their properties which were found to be accurate later.

The usefulness of Mendeleev's periodic table was confirmed by the discovery of elements with predicted properties.
Why are the hydrides of mendeleevs group 1 and 7 placed in separate groups?
Mendeleev left gaps in his table to place elements not known at the time. By looking at the chemical properties and physical properties of the elements next to a gap, he could also predict the properties of these undiscovered elements. For example, Mendeleev predicted the existence of 'eka-silicon', which would fit into a gap next to silicon. The element germanium was discovered later. Its properties were found to be similar to the predicted ones and confirmed Mendeleev's periodic table.
What was Mendeleev's contribution to the knowledge of elements?
When making his periodic table Mendeleev noticed some spaces where elements should be couldn't be filled. He didn't want to force elements that didn't belong there to go there, so he believed the spaces were undiscovered elements. He left the names blank but predicted their properties. Later the elements Mendeleev predicted existed were discovered.

What is the greatest triumph about mendeleev's periodic table?
The greatest triumph of Mendeleev's periodic table was his predictions of the existence of the undiscovered elements.

What made Mendeleev's discovery of the elements so revolutionary?
He made the first ever periodic table, that was the revolutionary thing Mendeleev made.-----01/6/2012Mendeleev's discovery about elements were so revolutionary because he left gaps for undiscovered elements. He predicted the elements properties to get the empty spaces that would later be proven true (the prediction of the other undiscovered elements) in 1875 by a scientist.
How did Dmitri Menedeleyev arrange elements on his first periodic table?
Mendeleev arranged the elements in a table with the rows ordered by atomic mass and the columns ordered the elements properties.
Was Dmitri Mendeleev able to predict undiscovered elements?
Dmitri Menedeleev was able to predict the properties of undiscovered elements because the periodic table organizes elements based on repeating properties. For example, all of the Noble Gases (the far-right column) have filled their valence electron shells and are inert gases. One could reasonably assume that if a new element was discovered that went in the noble gas column that it would be inert as well. Mendeleev used this concept to accurately predict the properties of a handful of undiscovered elements, such as Gallium and Germanium.
What elements properties can be predicted from?
An elements property can be best predicted from the group it is in the Periodic Table. Groups (the columns of the tables) of elements have similar properties due to their similar electron configuration of the valence shell.
