He predicted only 1 element. But you can look up that same question right here on this site. Hope this helps!

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.


Is the following sentence true or false Mendeleev used his periodic table to predict the properties of undiscovered elements. Today and Periodic Table?

True. Mendeleev used his periodic table to predict the properties of undiscovered elements by leaving gaps for them based on the patterns he observed in the properties of known elements. His predictions were later confirmed with the discovery of elements like gallium and germanium, which closely matched his forecasts. This ability to predict properties based on periodic trends is a key aspect of the periodic table's significance in chemistry.


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 able to find out for each element?

He was able to work out the atomic mass of the missing elements, and so predict their properties. And when they were discovered, Mendeleev turned out to be right. For example, he predicted the properties of an undiscovered element that should fit below aluminium in his table. When this element, called gallium, was discovered in 1875, its properties were found to be close to Mendeleev's predictions. Two other predicted elements were later discovered, lending further credit to Mendeleev's table.


How did Mendeleev predict the existence of unnatural elements?

Mendeleev predicted the existence of unnatural elements by leaving gaps in his periodic table for elements that had not yet been discovered. He used the properties of known elements around these gaps to infer the characteristics of the missing elements, thereby predicting their existence. This approach proved successful when later discoveries confirmed the existence of these predicted elements.

How did Mendeleev discover the patter that led to the periodic table?

Mendeleev arranged elements in order of atomic mass. He arranged elements in rows and columns that later helped in discovering modern periodic table.


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.


What did mendeleev discover?

Dmitri Mendeleev discovered the periodic law and created the periodic table of elements. He arranged elements by atomic mass and properties, leaving gaps for undiscovered elements which he later predicted and found to exist. This work laid the foundation for modern chemistry.


What do the long dashes represent on mendeleev's periodic table?

The long dashes on Mendeleev's periodic table represent gaps where elements had not yet been discovered but were predicted to exist based on the periodic pattern of elements. Mendeleev used these gaps to accurately predict the properties of the missing elements, leading to the discovery of new elements.

What is the greatest triumph about mendeleev's periodic table?

Dmitri Mendeleev's greatest triumph with the periodic table was his ability to predict the properties of undiscovered elements. Gaps in the table led him to propose the existence of new elements with specific characteristics, which were later discovered and matched his predictions, confirming the validity of his periodic law.

The first periodic table of elements Mendeleev created contained only 70 elements.ng?

Mendeleev's first periodic table contained 63 elements. He left gaps for undiscovered elements and predicted their properties based on the patterns of the known elements around them. Mendeleev's table was later expanded to include more elements as they were discovered.


Who create the first periodic table?

Mendeleev developed the first periodic table and Mosely later modernized it.
