What describes mendeleev use of the term eka-aluminum?
Gallium was named eka-aluminium by Mendeleev.
Which matches Mendeleev's prediction for the properties of eka-aluminum?
These characteristics were: density, melting point, atomic mass, type of oxide and chloride.
What are the blanks in Mendeleev's Periodic Table?
Mendeleev named the missing elements after elements in the same group. he gave the name eka-aluminum to the element that belonged one space below aluminum on the able. Mendeleev predicted that eka-aluminum would be a soft metal with a melting point at a density of 5.9 g/cm3. In 1875,a french chemist discovered a new element. He named the element gallium in honor of France. Gallium is a soft metal with a melting point of 29. degrees Celsius and a density o f5.91 g/cm3. So pretty much in short Mendeleev left blank spaces because of Gallium.
Name three sets of elements added to the periodic table after mendeleev's time?
Mendeleev predicted three elements namely Eka- aluminum (which turned out to be Gallium), Eka- boron (which turned out to be Scandium) and Eka- silicon (which turned out to be Germanium). Though these three elements are very famous, Mendeleev also predicted Eka- manganese (which turned out to be Technetium).
It must have taken some gall in 1871 for Mendeleev to predict the existence of this low-melting metal then four years later eka-aluminum was discovered by a Gallic chemist?
gallium

Which describes mendeleevs use of the term ekaaluminum?
A mixture of aluminum and an unknown element.
What is eka boron eka aluminum eka silicon?
eka aluminum is gallium eka boron is scandium eka silicon is germanium
Which matches Mendeleev's prediction for the properties of eka-aluminum?
These characteristics were: density, melting point, atomic mass, type of oxide and chloride.
What was Mendeleev's prediction for eka aluminum?
Mendeleev predicted that this chemical element is under aluminium and near zinc in the periodic table. The predictions for melting point, atomic mass, density etc. were correct.
What are the blanks in Mendeleev's Periodic Table?
Mendeleev named the missing elements after elements in the same group. he gave the name eka-aluminum to the element that belonged one space below aluminum on the able. Mendeleev predicted that eka-aluminum would be a soft metal with a melting point at a density of 5.9 g/cm3. In 1875,a french chemist discovered a new element. He named the element gallium in honor of France. Gallium is a soft metal with a melting point of 29. degrees Celsius and a density o f5.91 g/cm3. So pretty much in short Mendeleev left blank spaces because of Gallium.
What was the thing that was blank on Mendeleev's periodic table?
The elements which were not discovered at that time were made blank. Mendeleev named them as eka-aluminium, eka-silicon etc. They were discovered later and were placed in the gaps.

gallium
What was Mendeleev able to do with the gaps he left in the periodic table?
Mendeleev left those gaps for the elements which were not discovered at that time. He named those elements like eka-aluminium,eka -silicon etc.
Which elements did Mendeleev leave space for in his first periodic table?
Mendeleev left spaces for undiscovered elements. He named them eka-aluminium, eka-silicon etc.
