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 discovery showed that Mendeleev was correct in organizing his table of elements according to properties?
Gallium which had the properties that Mendeleev predicted
Is gallium a good natured element?
Gallium is just an element and as such it does not have either a good or bad nature, having a nature is a property of a thinking animal.
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.
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.
A man who accuratly predicted the properties of gallium?
mendeleev

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 effect did th discovery of gallium have on the accepteance of mendeleevs table?
Mendeleev had some empty spaces in his table. On being asked why he left spaces, instead of seeing it as a drawback, he confidently said that those were the places for "yet to be discovered elements". He named them by prefixing the Sanskrit numeral "Eka-" to the preceding element.For example, he named Gallium as "Eka-aluminium", Germanium as "Eka-Silicon" and so on. Later, when a new element was found and was named as Gallium, it was observed that it had almost same properties as that of Eka-Aluminium predicted by Mendeleev. As his predictions were almost accurate, other scientists began to accept that his classification was indeed better than any others'. And so, it was accepted.
Is gallium a good natured element?
Gallium is just an element and as such it does not have either a good or bad nature, having a nature is a property of a thinking animal.
Which describes mendeleevs use of the term ekaaluminum?
A mixture of aluminum and an unknown element.
Why germanium and silicon are not preferred in LEDs?
A: Because the element has different property as gallium arsenide.
