The validity of the Periodic Table of elements, which was originally devised by Mendeleev, has been confirmed by a vast body of chemical research. It would not be an exaggeration to say that everything in the science of chemistry conforms to Mendeleev's theory.
Mendeleev's predictions about the atomic weights of his yet-to-be-found "eka" elements were proven correct first when his "eka-aluminum", which he predicted would have a weight of about 5.94 (that is, 5.94 times heavier the water), was measured at an abnormally close number of 5.91.
He said that te three new elements would be discovered, and he described their properties.
Dmitri Mendeleev made many predictions about the location of unknown elements on the periodic table. It would take 20 years for the undiscovered ekasilicon to be found and named Germanium.
He said that three new elements would be discovered, and he described their properties
Hun,..I am positive thatyou are smart enough! I promise! God gave you brains... you just have to know when to use them:) this would be the time to use em'...:D
He predicted that Three new elements would be discovered and he described their properties.
Mendeleev predicted following:-
1. Existence of noble gases
2. Existence of other elements like gallium, Germanium
it proved that his idea was potentially right
Those are theories that are possibly right, but not proved correct yet.
i have no idea but i will check and keep you posted.
Dmitri Mendeleev only wrote many books, somewhere around the number of 250 publications. His most famous work is the book "Organic Chemistry" that was published when Mendeleev was 27 years old.
i need help
Because he manged to predict it being there so he was proved right and proved a genius!
Copper and magnesium are elements that were difficult for Mendeleev to add to his table because they were found to combine in various ratios with other elements.copper and manganese
Balboa
The atomic theory that was supported by Mendeleev when scientist found the elements that Mendeleev predicted was out there in the world. When Mendeleev made the periodic table he left spots for elements he did not have but knew would be found one day.
it proved that his idea was potentially right
what events proved that Metternich was correct in his fears
Myths
He was Russian
Dmitri Mendeleev
Dmitri Mendeleev performed his research during the year 1847.
Paul Elrich was proved right in 1909.
Mendeleev did not predict the properties of silicon.
