What did Mendeleev predict about the periodic table?
Dmitri Mendeleev predicted the existence and properties of several elements that were later discovered and filled gaps in the periodic table. He also predicted the properties of these elements based on their position in the 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.
From gaps in his table mendeleev predicted the existence of several elements and their?
properties. Mendeleev's periodic table had gaps for elements that had not been discovered yet, but he was able to predict their properties based on the patterns of the elements surrounding the gaps. This led to the discovery of new elements like gallium, germanium, and scandium.
Mendeleev left spaces in his periodic table and predicted several elements and they're?
Yes, Mendeleev left gaps in his periodic table to accommodate elements that had not yet been discovered. Some of the elements he predicted include germanium, gallium, and scandium. These predictions were largely based on the properties of neighboring elements in the table.
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.
Development of periodic table?
The periodic table was first developed by Russian chemist Dmitri Mendeleev in 1869. He arranged the elements based on their atomic mass and properties and predicted the properties of missing elements. Over time, the periodic table has been modified and expanded based on the discovery of new elements and advancements in atomic theory.
Who agreed with Dmitri Mendeleev's theories?
Mendeleev's periodic table was widely accepted by the scientific community, particularly after he accurately predicted the properties of several missing elements. Among those who agreed with his theories were chemists Julius Lothar Meyer and William Ramsay. Mendeleev's periodic table provided a comprehensive framework for understanding the relationships between elements based on their properties.
Mendeleev's periodic table was 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 true or false?
True.
How periodic table was invented?
The Periodic Table was invented by Dmitry Mendeleyev. He grouped every known element and he used this table to predict the existence of other several elements. Mendelevium name pays homage to Dmitry Mendeleyev.
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.
Predicted to occor?
several things have been predicted to occurr very soon... bad things mostly... pray ever day and all is well.
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.
