What element did Mendeleev predict before it was discovered?
Mendeleev predicted that gallium belonged to the R2O3. Gallium was not discovered until 1874. The noble gases weren't discovered until 1894 through 1899.
What were mendeleevs discoveries and predictions and discoveries abot the periodic table?
Mendeleev predicted that properties of elements are periodic function of atomic mass. He demonstrated it by creating a table.
Which is a property that Mendeleev's predicted for gallium?
Examples: density, melting point, atomic weight, density and formula of oxide.
Which discovery showed that Mendeleev was correct in organizing his table of elements according to properties?
Gallium which had the properties that Mendeleev predicted
What kinds of predictions did Mendeleev make using his table?
By placing the elements in order of their Atomic Mass then grouping them based on similar chemical properties, Mendeleev recognized that there were gaps in the pattern he made where elements should be. He predicted there were some elements yet to be discovered and predicted their chemical properties. The elements he predicted were later discovered and named germanium, gallium, and scandium.
What is a property that Mendeleev predicted for gallium Ga metal gas nonmetal or highly reactive?
Mendeleev predicted that gallium will be a metal.
A man who accuratly predicted the properties of gallium?
mendeleev
Which is property that mendeleev predicted for gallium?
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.

What effect did the discovery of the gallium have on the acceptance of Mendeleev's table?
The close match between Mendeleevs prediction and the actual properties of new elements showed how usefullhis pariodic tabel could be.

What is the name of the compound GaCl3?
The best name is gallium trichloride. Gallium has another chloride GaCl2
What is the chemical name of GaF3?
This compound is gallium trifluoride.
What is the modern name of ekaaluminium?
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).
