The element discovered by Mendeleev in 1871 was germanium. Mendeleev predicted the existence of this element and its properties before it was actually discovered.
Mendeleev predicted the existence and properties of germanium by leaving gaps in his periodic table for elements that had not yet been discovered. He correctly deduced the properties of the missing element based on the pattern of elements around its position in the table. When germanium was discovered, its properties closely matched Mendeleev's predictions, confirming the validity of his periodic table.
Dmitri Mendeleev, a Russian chemist, discovered the periodic law and created the periodic table of elements in 1869. Mendeleev's table arranged elements based on their atomic mass and predicted the existence and properties of undiscovered elements.
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 used the properties of gallium, scandium, and germanium to predict their existence before they were discovered. Their discovery and properties helped confirm the accuracy of Mendeleev's periodic table and his periodic law. This further solidified Mendeleev's contributions to the development of the modern periodic table.
Mendeleev proposed that there must be missing elements, to which he gave the provisional names Ekaboron, Ekaaluminum and Ekasilicon. Scankium, Gallium and Germanpoop were discovered in 1879, 1875 and 1886, respectively, with properties very close to those predicted by Mendeleev. hey Glen
The element discovered by Mendeleev in 1871 was germanium. Mendeleev predicted the existence of this element and its properties before it was actually 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.
Mendeleev couldn't predict the existence of noble gases because they are inert and do not readily form compounds with other elements. Mendeleev's periodic table was based on the properties of elements and their compounds, and since noble gases do not readily form compounds, they did not fit into his classification scheme.

You think probable to Dimitri Mendeleev.
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.

Mendeleev left gaps for undiscovered elements. He predicted their properties which were found to be accurate later.
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 used the properties of gallium, scandium, and germanium to predict their existence before they were discovered. Their discovery and properties helped confirm the accuracy of Mendeleev's periodic table and his periodic law.
