The first time polonium was obtained by Marie and Pierre Curie in 1898, separating polonium from uranium ores. Now polonium is obtained by nuclear reactions.
Polonium can be separated from uranium ores but is a very difficult and expensive procedure. Polonium can be also obtained by nuclear reactions.
More than hundred years ago polonium was obtained from the uranium ores; now plutonium is obtained artificially, by nuclear reactions.
Polonium is obtained now only as a result of nuclear reactions; the total world production is 100-200 g/year. Consequently the price is enormous.
Polonium is a nonmagnetic element.
Polonium is an amphoteric chemical element. Also is a member of the chalcogens elements family (group 16 in the periodic table of Mendeleev) and tellurium is also a metalloid.
Polonium is considered generally a metalloid.
Data about the hardness of polonium don't exist.
In the past polonium was obtained from the residues of uranium ores, after extraction of uranium.Now polonium is obtained only by nuclear reactions.
The first time polonium was obtained by Marie and Pierre Curie in 1898, separating polonium from uranium ores. Now polonium is obtained by nuclear reactions.
Today polonium is obtained only artificially, especially in Russia.
Polonium can be obtained by artificial methods. It is not renewable.
Now polonium is not obtained from natural sources; it is the product of some nuclear reactions.
Natural polonium was isolated from residues resulted after the extraction of uranium from ores; the process is long and tedious. Today polonium is obtained artificially.
Polonium is a radioactive chemical element, extremely rare, accompanying uranium in some ores; now polonium is obtained by nuclear reactions.
Polonium is a natural chemical element but can be also obtained artificially.
The most common reaction to obtain polonium is;Bi-209 + n------------Bi-210-----------------Po-210 + e-
Now polonium is not extracted from uranium ores; polonium is more simple prepared by nuclear reactions.
No, after the alpha decay of polonium lead isotopes were obtained.
The isotope lead-204 is obtained.
