Mendeleev in his periodic table left some spaces below Al and called it as Eka Al ( presently it is the Gallium ). By this name he tells the up coming chemists that there is a new element with the property of Aluminium.Thus he contributes in discovery of Gallium...!
The discovery of germanium was important for Mendeleev's periodic table because its properties matched the gaps he had predicted in his table. This provided evidence for the periodicity of elements and the accuracy of Mendeleev's arrangement. Germanium's discovery also helped validate the periodic law which states that the properties of elements are periodic functions of their atomic numbers.
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.
The discovery of germanium was important because it filled a gap in the periodic table, demonstrating the usefulness of Mendeleev's periodic law. Germanium's properties as a semiconductor also made it a crucial element for the development of early electronic devices like transistors, paving the way for modern technology.
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.
The element discovered by Mendeleev in 1871 was germanium. Mendeleev predicted the existence of this element and its properties before it was actually discovered.
The discovery of undiscovered elements with properties predicted by Mendeleev's periodic table (like gallium, germanium, and scandium) confirmed the accuracy of his organization. These elements filled gaps in the periodic table and established a pattern of periodicity that supported Mendeleev's initial insights.

Gallium and germanium were important to Mendeleev because their properties fit well into his periodic table, filling the gaps he had predicted based on the patterns of other elements. The discovery and confirmation of these two elements helped validate his periodic law and strengthen his periodic table's credibility.
Mendeleev predicted the atomic mass of germanium to be approximately 68 g/mol. The actual atomic mass of germanium is about 72.63 g/mol. This results in a difference of roughly 4.63 g/mol between Mendeleev's prediction and the actual value.
i have no idea but i will check and keep you posted.

The holes suggested that there were "missing" elements that hadn't been discovered yet. Mendeleev successfully predicted the basic properties of germanium, which hadn't been discovered at the time, based on the properties he expected an element in that position to have. He called it "eka-silicon" (eka is a Sanskrit word meaning "one", because it was one period "higher" than silicon).When germanium was later discovered and turned out to have properties very similar to what Mendeleev had predicted, it went a long way towards validating Mendeleev's concept.
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 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
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.
