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.
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.
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.
DiscoVery of new elements
He left too many spaces between the elements......
Dmitri Mendeleev figured out that there were missing elements on his periodic table. Using periodic trends and averaging numbers, he could make pretty accurate predictions about elements not discovered yet. Mendeleev predicted four: * ekaboron (modern day scandium) * ekaaluminium (modern day gallium) * ekamanganese (modern day technetium) * ekasilicon (modern day germanium)
It would be a soft metal with a low melting point.
A mixture of aluminum and an unknown element.
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.
Eka-aluminum corresponds to the element gallium. Gallium is located below aluminum in the periodic table and shares similar chemical properties with eka-aluminum.
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.
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.
Gallium was named eka-aluminium by Mendeleev.

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.
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.
Gallus,Galij, or eka-aluminum It is also called Gallia meaning France in French or Latin
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.
