An element's properties can be predicted based on its position in the Periodic Table, which is organized by increasing atomic number and similar chemical behavior. Elements with similar properties tend to be grouped together in columns, called groups, and rows, called periods. The arrangement of elements in the periodic table allows scientists to make predictions about an element's properties based on its location relative to other elements.
What else can I help you with?
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.
Who listed the elements in a table accourding to their atomic masses?
Mandeleev who predicted periodic table.
How did this Russian scientist first arrange the elements?
Dmitri Mendeleev arranged the elements in his periodic table based on their atomic masses and chemical properties. He left gaps for undiscovered elements and predicted their properties accurately.
Why was Mendeleev's periodic table accepted by most chemists?
Mendeleev's periodic table was accepted because it accurately predicted the properties of unknown elements and left spaces for them, demonstrated the periodicity of elements based on atomic mass, and was flexible enough to accommodate newly discovered elements. Its predictive power and organization of elements based on their physical and chemical properties made it successful and widely accepted.
Why was Mendeleev's decision to leave blank spaces on his table sometime referred to as his most significant contribution to periodic table?
Mendeleev thought about the future and realized that it was entirely unlikely that all earthly elements had been discovered, so he left blank spaces in his table and even predicted some of the elements that would fit in those spaces. Surprisingly enough, as time passed, chemists began discovering many of the elements that he had predicted, which fit perfectly into his periodic table.
What are some of the uses of the periodic table of elements?
- allowed rational ordering of chemical elements- predicted the properties of unknown elements- the chemical behavior of chemical elements can be predicted- the atomic radius can be predicted- the melting point can be predictedand more
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.
Why were some of the elements not predicted?
Some elements were not predicted because they were unstable and quickly decayed into other elements, making them difficult to observe or study. Additionally, some elements exist in very small quantities or under extreme conditions that were not present when the periodic table was initially created.
What did the gaps on Mendeleev's tabel represent?
He predicted that elements with the predicted properties would be discovered to fill in these gaps.
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.
What properties can be predicted by the elements place on the periodic table?

Who predicted that the existence of several missing elements?
You think probable to Dimitri Mendeleev.
Did Mendeleev fix the problem of predicted where new elements would fit into the periodic table?
Yes, Dimitri Mendeleev did (accurately, I might add) predict where elements would appear in his table. He also correctly predicted some of the missing elements' properties, based on where they were positioned in his table.
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)
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.
Did Mendeleev leave gaps in the table for undiscovered elements?
Yes, Mendeleev left gaps in his periodic table for undiscovered elements. He predicted the properties of these missing elements based on the trends in the known elements and their positions in the table. This helped in the discovery of elements such as gallium, scandium, and germanium.
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.
