This is a very wordy response, but by setting up the Periodic Table according to elements' properties and characteristics, he was able to predict any given elements' properties because, with the way the Periodic Table is arranged, all of the elements surrounding any specific element would have similar properties to the element that they surrounded.
For example, at the time there was no element known as Aluminum, but given the properties of the elements around that area (Group 13), he was able to correctly predict Aluminum's properties. When aluminum was discovered, Mendeleev's predictions were extremely close to the actual element's properties.
What else can I help you with?
How could Mendeleev make predictions about the properties of undiscovered elements?
Mendeleev arranged the known elements by increasing atomic mass and grouped elements with similar properties together. Gaps in the table indicated elements that were yet to be discovered. By observing the patterns in the properties of known elements within each group, Mendeleev was able to predict the properties of the undiscovered elements that would fill these gaps.
How could Dmitri Mendeleev predict the properties of elements that had not yet been discovered?
Dmitri Mendeleev predicted the properties of undiscovered elements by arranging known elements in his periodic table based on their atomic mass and chemical properties. Gaps in the table suggested the existence of unknown elements with specific characteristics based on the trends observed. This systematic approach allowed Mendeleev to make accurate predictions about the properties of elements yet to be discovered.
How could Mendeleevs table be used to predict the properties of elements that had not been discovered?
Mendeleev's periodic table allowed for the prediction of the properties of unknown elements by identifying gaps in the table where elements had not yet been discovered. By examining the properties of neighboring elements, Mendeleev was able to predict the properties of the missing elements and suggest their existence. His periodic table provided a framework for organizing elements based on their atomic mass and chemical properties, which allowed for the accurate prediction of the properties of undiscovered elements.
What important scientific discovery did dimitri mendeleev make about materials?
Dmitri Mendeleev discovered the periodic law and created the first version of the periodic table of elements, organizing known elements by increasing atomic mass and predicting properties of undiscovered elements.
Why did Dmitri make the periodic table?
Dmitri Mendeleev arranged the elements known at that time in the increasing order of atomic masses and repeating properties, so that it is easier to classify and study the properties of the elements.
How could Mendeleev make predictions about the properties of undiscovered elements?
Mendeleev arranged the known elements by increasing atomic mass and grouped elements with similar properties together. Gaps in the table indicated elements that were yet to be discovered. By observing the patterns in the properties of known elements within each group, Mendeleev was able to predict the properties of the undiscovered elements that would fill these gaps.
Why was mendeleev unable to make any predictions about the noble gas elements?
The reason that Mendeleev didn't make any predictions about the gases was that these gases were not even discovered yet, therefore it was impossible for Mendeleev to make predictions.----Dmitri Mendeleev made his predictions on what would fill the gaps on his far from perfect periodic table. He predicted their sizes, weights, appearances, etc.I think the reason he didn't make predictions is because noble gases are not visible, and weightless.-------------------------------Mendeleev couldn't predict the noble gases' properties because their existence wasn't known, as implied above.Argon, a noble gas, was noticed twenty-five years later by John William Strutt and Sir William Ramsey (the names are not really important).It doesn't matter that the elements weren't discovered. That's the whole point of arranging the elements. To PREDICT the properties of the missing/unknown ones.
Why was Mendeleev's periodic table widely accepted?
Mendeleev ordered the elements according to increasing atomic mass in vertical and horizontal rows. The horizontal rows contained analogous elements. This system was clear and consistent, and was superior because the number of protons, the most massive particle in atoms, is actually what distinguishes each element.
What kinds of predictions did Mendeleev make using his table?
By placing the elements in order of their Atomic Mass then grouping them based on similar chemical properties, Mendeleev recognized that there were gaps in the pattern he made where elements should be. He predicted there were some elements yet to be discovered and predicted their chemical properties. The elements he predicted were later discovered and named germanium, gallium, and scandium.
How could Dmitri Mendeleev predict the properties of elements that had not yet been discovered?
Dmitri Mendeleev predicted the properties of undiscovered elements by arranging known elements in his periodic table based on their atomic mass and chemical properties. Gaps in the table suggested the existence of unknown elements with specific characteristics based on the trends observed. This systematic approach allowed Mendeleev to make accurate predictions about the properties of elements yet to be discovered.
How Mendeleev used the data available to him to create his periodic table?
Mendeleev placed his elements in order of increasing atomic mass. He placed elements with similar chemical properties in the same groups or families. He realized that there were some gaps in the table where an undiscovered element should go and made predictions about those elements before they were found.
What did the Russian scientist Mendeleev create the periodic table?
Dmitri Mendeleev created the periodic table to organize and classify the known elements based on their properties and atomic weights. He left gaps for undiscovered elements and successfully predicted the properties of some of these missing elements.
Why were Mendeleevs efforts on the peridic table more successfully the other scientist?
Mendeleev's table was more systematic. Elements were arranged in order of atomic masses.
How could Mendeleevs table be used to predict the properties of elements that had not been discovered?
Mendeleev's periodic table allowed for the prediction of the properties of unknown elements by identifying gaps in the table where elements had not yet been discovered. By examining the properties of neighboring elements, Mendeleev was able to predict the properties of the missing elements and suggest their existence. His periodic table provided a framework for organizing elements based on their atomic mass and chemical properties, which allowed for the accurate prediction of the properties of undiscovered elements.
Which were the elements predicted by Mendeleev and what name did he give them?
Dmitri Mendeleev figured out that there were missing elements on his periodic table. Using periodic trends and averaging numbers, he could make pretty accurate predictions about elements not discovered yet. Mendeleev predicted four: * ekaboron (modern day scandium) * ekaaluminium (modern day gallium) * ekamanganese (modern day technetium) * ekasilicon (modern day germanium)
What important scientific discovery did dimitri mendeleev make about materials?
Dmitri Mendeleev discovered the periodic law and created the first version of the periodic table of elements, organizing known elements by increasing atomic mass and predicting properties of undiscovered elements.
What is the process mendeleev used to make the periodic table?
Dmitri Mendeleev organized the periodic table by arranging elements in order of increasing atomic mass and grouping elements with similar properties together. He left gaps in the table for undiscovered elements and predicted the properties of these elements based on the patterns he observed in the table.
