Question

Answer

Prediction of Eka Aluminium by Mendeleev

Mendeleev was a Russian chemist who is known for his contribution in the development of the periodic table. He predicted the existence of several elements that were not known at that time. One of them was Eka Aluminium.

Explanation

Eka Aluminium is the name given by Mendeleev to the element that he predicted to exist between Aluminium and Gallium. This element was later discovered and named Gallium, which has the atomic number 31 and is denoted by the symbol Ga.

Gallium has some properties that are similar to Aluminium, such as its low density and its ability to form alloys with other metals. However, it also has some unique properties, such as its low melting point and its ability to liquefy at room temperature.

Conclusion

In conclusion, Mendeleev's prediction of Eka Aluminium was a remarkable achievement in the field of chemistry. The discovery of Gallium, which was predicted by Mendeleev, not only validated his periodic table but also helped in the development of the modern periodic table.

Answer

The undiscoverd  elements at that time  for which gaps were left in the periodic table were left in the periodic table were named by mendeleev as eka-boron ,eka- aluminium by prefixing the term 'eka' to the name of the preceding element in the same group.when this element were discoverd lateron.then the eka-aluminium was named as gallium.... Gallium (eka aluminium ).and germanium (eka -silicon).Thier properties  were predicted on this basis of their positions in mwndeleev's periodic table...

Answer

Eka aluminium predicted by Mendeleev is Gallium. Eka-aluminium and gallium are the two names of the same element as Eka -Aluminum has almost exactly the same properties as the actual properties of the gallium element.

Answer

Eka means same mendeleeve predict in his periodic table that in future there will be an element whose properties will same like aluminium.....eka means same

Answer

Eka aluminum is gallium, Eka silicon is germanium. their properties are aluminum exist as Al2o3 and gallium exist as Ga2o3, and also like silicon exists as sio2, germanium exists as Geo2, like carbon it exists as cH4, Geo4
