It is quite true that you can use the Periodic Table to predict the chemical properties of undiscovered elements, but this is not of any great practical importance because any remaining undiscovered elements are going to be so heavy that they will be very unstable, and will rapidly decay into other, lighter elements. All elements having a stable nucleus have already been discovered. Once you get to elements heavier than uranium, they just get more and more unstable, the heavier they get.
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.
Mendeleev was able to predict the properties of the yet unknown element (Germanium) by the properties of the surrounding known elements on his periodic table of the elements. Predicting properties such as reactivity, density, atomic mass, etc., he knew where the undiscovered element would be placed.
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.
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.
Mendeleev placed arsenic and selenium on the periodic table based on their chemical properties and atomic masses. He arranged elements by increasing atomic mass and grouped them by similar properties. By doing so, he could predict the properties of undiscovered elements and fill in gaps in the periodic table.

True. Mendeleev and other scientists used the periodic table to predict the properties of undiscovered elements based on their position in the table. This led to the successful discovery and confirmation of elements like gallium and germanium.
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.
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.
Mendeleev organized his periodic table by atomic mass and similar chemical properties of elements to recognize patterns and trends. He arranged the elements in horizontal rows and vertical columns based on these properties, allowing him to predict the properties of undiscovered elements.
In 1869, Dmitri Mendeleev arranged the elements in a periodic table based on their atomic weights and noticed that the properties of the elements appeared at regular intervals. This led him to predict the properties of undiscovered elements and paved the way for the modern periodic table we use today.
Mendeleev was able to predict the properties of the yet unknown element (Germanium) by the properties of the surrounding known elements on his periodic table of the elements. Predicting properties such as reactivity, density, atomic mass, etc., he knew where the undiscovered element would be placed.
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.
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.
Dmitri Mendeleev is most known for creating the periodic table of elements, which he organized based on atomic weight and properties, and predicted the properties of undiscovered elements. His work laid the foundation for modern chemistry and our understanding of the elements.
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.
Dmitri Mendeleev created the first periodic table of elements in 1869. He arranged elements by increasing atomic weight and grouped those with similar properties together. Mendeleev left gaps for undiscovered elements and was able to predict the properties of these missing elements.
