In the past protactinium was extracted from the residues of uranium ores; now is extracted from thorium irradiated in nuclear reactors.
In the past protactinium was extracted as a by-product from uranium ores. Today is obtained by a nuclear reaction in reactor.
Protactinium is a metal.
Protactinium hasn't an odor.
Because the properties (chemical and physical) of protactinium are the general properties of metals.
Protactinium is a solid metal.
In the past protactinium was extracted as a by-product from uranium ores. Today is obtained by a nuclear reaction in reactor.
Protactinium is a natural chemical element but now is obtained in nuclear reactors.
Now protactinium is prepared by the following reaction:Th-232 + n-------------Th-233-----------Pa-233
Now protactinium is obtained by a nuclear reaction:Th-232 + n------------Th-233--------------Pa-233
Protactinium is not corrosive.
Protactinium have no odor.
Protactinium is paramagnetic.
