Dmitri Mendeleev was able to predict the properties of germanium by leaving gaps in his periodic table for elements that were yet to be discovered. He noticed a pattern in the properties of known elements and used this pattern to predict the existence and properties of undiscovered elements, such as germanium.
Mendeleev did not predict the properties of silicon.
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.
Independently by Dmitri Mendeleev and Lothar Meyer in 1869
Dmitri Mendeleev
He used the difference method
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.
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.
Mendeleev attempted to organize the chemical elements based on their atomic mass and properties, creating the periodic table. He arranged the elements in rows and columns with similar properties to create patterns and predict the properties of unknown elements.
