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.
Mendeleev predicted that gallium belonged to the R2O3. Gallium was not discovered until 1874. The noble gases weren't discovered until 1894 through 1899.
Mendeleev predicted that properties of elements are periodic function of atomic mass. He demonstrated it by creating a table.
The chemical name for GaBr3 is gallium tribromide.
Examples: density, melting point, atomic weight, density and formula of oxide.
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)
mendeleev
Mendeleev predicted that gallium (Ga) would have properties of a metal based on its position in the periodic table. Gallium exhibits characteristics of a metal, such as being solid at room temperature, having a metallic luster, and conducting electricity.
The fundamental properties that Mendeleev predicted for gallium was that it would be a bright metal color and it would have a high boiling point. It would also have a relative density of 5.5 and an atomic mass of 72.
Mendeleev predicted that gallium belonged to the R2O3. Gallium was not discovered until 1874. The noble gases weren't discovered until 1894 through 1899.
The close match between Mendeleevs prediction and the actual properties of new elements showed how usefullhis pariodic tabel could be.

gallium (III) orthophosphate
Mendeleev predicted that properties of elements are periodic function of atomic mass. He demonstrated it by creating a table.
The modern name of Ekaaluminium is Gallium. Mendeleev discovered Gallium in 1875. He also discovered Ekaboron (now known as Scandium), and Ekasilicon (now known as Germanium).
The chemical name for GaBr3 is gallium tribromide.
