What describes mendeleev use of the term eka-aluminum?
Mendeleev used the term "eka-aluminum" to predict the properties of an undiscovered element that would have similar characteristics to aluminum. This was part of his periodic table where he left gaps for undiscovered elements. Eka-aluminum was later discovered and named gallium, confirming Mendeleev's periodic trends.
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?
Mendeleev predicted the existence of eka-aluminum (later named gallium) in 1871 based on gaps in his periodic table. Four years later, in 1875, French chemist Paul-Émile Lecoq de Boisbaudran discovered gallium which had similar properties to the predicted eka-aluminum. This discovery validated Mendeleev's periodic table and his prediction methods.
Which matches Mendeleev's prediction for the properties of eka-aluminum?
Eka-aluminum corresponds to gallium, which was discovered later by Lecoq de Boisbaudran. Gallium's properties closely match Mendeleev's predictions, such as its atomic weight and properties lying between aluminum and indium in the periodic table.
What prediction did Mendeleev make that came true less then 20 yrs later?
he predicted the places where he knew elements should be but he couldn't visibly see. Back when Mendeleev was alive, what you could not see you could not measure. This explains why he couldn't see the noble gasses.
What is eka boron and eka silicon?
"Eka boron" and "eka silicon" are placeholder names given to hypothetical elements predicted by Dmitri Mendeleev in his periodic table before their actual discovery. Eka boron is now known as Scandium, while eka silicon is now known as Germanium.
What describes Mendeleev's use of term eka-aluminum?
Gallium was named eka-aluminium by Mendeleev.

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 boron, eka aluminum, and eka silicon are theoretical elements predicted by Mendeleev's periodic table to fill in the gaps in the periodic table. They were later discovered and named as Scandium, Gallium, and Germanium, respectively.
What known element corresponds to eka-aluminum on the modern periodic table?
Eka-aluminum corresponds to the element gallium on the modern periodic table. Eka-aluminum was a placeholder name given by Dmitri Mendeleev for an element that he predicted would have properties similar to aluminum but with a higher atomic mass. Gallium, discovered in 1875, fits these properties and is known as eka-aluminum's modern counterpart.

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 prediction did Mendeleev make that came true less then 20 yrs later?
he predicted the places where he knew elements should be but he couldn't visibly see. Back when Mendeleev was alive, what you could not see you could not measure. This explains why he couldn't see the noble gasses.
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.
What element corresponds to eka-aluminum?
Eka-aluminum corresponds to the element gallium. Gallium is located below aluminum in the periodic table and shares similar chemical properties with eka-aluminum.
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.
