Why was the discovery of germanium important for Mendeleev's table?
Because he manged to predict it being there so he was proved right and proved a genius!
What did Dmitri Mendeleev find when he organized the elements by mass?
I believe the correct answer is he was able to predict the existence of yet undiscovered elements, due to the gaps. For instance, I believe germanium was one of the elements undiscovered in the table, its placeholder was called ekasilicon.
What do we now call eka-silicon?
What Mendeleev called ekasilicon is now called Germanium (Ge).
What family is carbon silicon germanium tin and lead in?
They are members of the group 14 of the periodic table of Mendeleev.
What describes Mendeleev and use of the term Eka aluminum?
mixture of aluminum and an unknown element later called Germanium.
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.

What element did Mendeleev predict before it was discovered?
Mendeleev predicted that gallium belonged to the R2O3. Gallium was not discovered until 1874. The noble gases weren't discovered until 1894 through 1899.
How did Mendeleev place germanium on the periodic table?
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.
How did Mendeleev predict the properties of silicon?
Mendeleev did not predict the properties of silicon.
Why did Mendeleev leave a space for the unknown at the time element germanium in his periodic table?
Because germanium was not known at the time when Mendeleev formulated his periodic table.
Why did mendeleev not include germanium in the periodic table?
He could not because it had not yet been discovered when he created the table. However he was able to determine that an element was missing at that location and predict the properties it would have when it was discovered. When germanium was discovered and named, his predictions were found to be very accurate.
What did Mendeleev predict about the periodic table?
The gaps in the first periodic elements described those elements which were not discovered at that time. Eg-silicon,germanium etc
How did Mendeleev's table predict properties?
luck
What elements predict the properties of ekasilicon?
Gallium and arsenic because they are ekasilicon's closest neighbors, and would therefore have very similar properties
What did Dmitri Mendeleev find when he organized the elements by mass?
I believe the correct answer is he was able to predict the existence of yet undiscovered elements, due to the gaps. For instance, I believe germanium was one of the elements undiscovered in the table, its placeholder was called ekasilicon.
How did many elements did Mendeleev predict would be discovered?
