What properties did mendeleev predict for eka-silicon?
Mendeleev predicted that eka-silicon, which we now know as germanium, would have properties similar to silicon. He anticipated that it would be a grayish-white metal, possess a density of around 5.5 g/cm³, and have a melting point higher than silicon's. Additionally, he expected eka-silicon to exhibit similar chemical behavior, including the formation of compounds analogous to those of silicon. Mendeleev's predictions about eka-silicon were largely confirmed when germanium was discovered in 1886.
Was Mendeleev's periodic table accurate enough that he was able to use it to predict the existence and several properties of certain elements that had not yet been 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.
Why were the holes in mendeleev's table important?
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.
Who arranged the elements by atomic mass and used it to predict properties of missing elements?
Independently by Dmitri Mendeleev and Lothar Meyer in 1869
How was it possible that Mendeleev was able to predict the properties of element no one knew about?
If I knew I wouldn't be asking!
Which elements would you use to predict properties of ekasilicon?
Ekasilicon was the name appointed by Mendeleev to the undiscovered germanium; germanium has similar chemical properties to silicon and tin.

How was Dmitri Mendeleev able to predict the properties of 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.
Why are the hydrides of mendeleevs group 1 and 7 placed in separate groups?
Mendeleev left gaps in his table to place elements not known at the time. By looking at the chemical properties and physical properties of the elements next to a gap, he could also predict the properties of these undiscovered elements. For example, Mendeleev predicted the existence of 'eka-silicon', which would fit into a gap next to silicon. The element germanium was discovered later. Its properties were found to be similar to the predicted ones and confirmed Mendeleev's periodic table.
