Yes, Dimitri Mendeleev (1834-1907) was alive during the discovery of radon (1899-1903).
The element radium (symbol Ra) is in period 7.
Radon was discovered in 1900 by Friedrich Ernst Dorn, a German chemist.
Mendeleev realized that some elements had not been discovered.
Only some elements were discovered during the life of Mendeleev.
No, Dmitri Mendeleev did not know about protons. The concept of protons was not discovered until later in the 20th century, after Mendeleev's time. Mendeleev is most famous for creating the periodic table of elements.
The element discovered by Mendeleev in 1871 was germanium. Mendeleev predicted the existence of this element and its properties before it was actually discovered.
i have no idea but i will check and keep you posted.
Immediately after the discovery of the radioactivity of radon, near 1900.
Radon was discovered in 1900 by Friedrich Ernst Dorn, a German chemist.
The element radium (symbol Ra) is in period 7.
Radon is the heaviest member of the noble gases group.Position in the Mendeleev periodic table of the elements: group 18, period 6, block p.
Radon is the heaviest member of the noble gases group.Its position in the Mendeleev Periodic Table of Elements is group 18, period 6, block p.
