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 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.
Which matches Mendeleev and prediction for the properties of eka-aluminum?
Mendeleev predicted the properties of eka-aluminum (now known as gallium) based on its position in the periodic table and the trends he observed in neighboring elements. He anticipated that eka-aluminum would have an atomic weight of around 68, a density similar to that of aluminum, and exhibit characteristics such as being a metal with a low melting point. When gallium was later discovered, its properties matched Mendeleev's predictions closely, confirming his foresight regarding the periodic relationships among elements.
What was the name predicted for gallium by mendeleevs?
Mendeleev predicted the name "eka-aluminium" for the element that is now known as gallium. This naming convention was based on the positions of the elements in his periodic table.
Which matches mendeleev prediction of the properties of eka-aluminium?
Mendeleev predicted the properties of eka-aluminium, which we now know as gallium, based on its position in his periodic table. He anticipated that eka-aluminium would have an atomic weight of about 68, a density of approximately 5.9 g/cm³, and would form compounds similar to aluminium, such as a trichloride. When gallium was discovered, its properties closely matched Mendeleev's predictions, confirming the validity of his periodic table and the existence of undiscovered elements.
What value was there in predicting the properties for gaps in Mendeleevs table?
DiscoVery of new elements
Which matches Mendeleevs prediction for the properties of eka-aluminum?
It would be a soft metal with a low melting point.
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 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 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.
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.
Which matches Mendeleev and prediction for the properties of eka-aluminum?
Mendeleev predicted the properties of eka-aluminum (now known as gallium) based on its position in the periodic table and the trends he observed in neighboring elements.

What describes Mendeleev's use of term eka-aluminum?
Gallium was named eka-aluminium by Mendeleev.
What is the current name for-eka-aluminum?
gallium
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.
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 another name for Gallium?
Gallus,Galij, or eka-aluminum It is also called Gallia meaning France in French or Latin
