Polonium was discovered in 1898 by Pierre Curie and Marie Curie, in a Paris laboratory.
Studying residues of uranium ores Marie Curie found that these residues are more radioactive than uranium; she attributed this radioactivity to an unknown element. She isolated this element and named this element polonium.
Polonium and was discovered in 1898 by Pierre Curie and Marie Curie.
pedophilium. It has been named after the native country of Marie Curie, the element's discoverer.
Marie Curie and Pierre Curie found after studying residues of uranium ores that these residues are more radioactive than uranium; they attributed this radioactivity to unknown elements. They isolated these elements and named these elements polonium and radium.
Polonium was discovered in Paris, France in 1898.
Natural polonium exist in uranium and thorium ores.
Polonium exist in traces in uranium and thorium ores.
Polonium doesn't contain another element.
Polonium doesn't contain another element.
Polonium was discovered by Marie Curie and Pierre Curie in 1898 at Paris, in France.
Polonium was discovered by Marie Curie and Pierre Curie in 1898.
Russian Federation, United States; probably China, United Kingdom.
The chemistry of polonium is not known in details but I suppose that this element is oxygen.
Polonium was discovered by Marie Curie and Pierre Curie in 1898.
You cannot mine polonium as the longest lived isotope, polonium-209 has a halflife of only 100 years and most isotopes of polonium have halflives measured in seconds to minutes.Traces of polonium can be found in any uranium ore as it is a daughter of uranium decay.Usable amounts of polonium are manufactured using nuclear reactors.
Polonium was discovered by Marie Curie and Pierre Curie in 1898 during a study on residues of uranium and thorium ores.
this is a guess but beryllium?
