Overview
Protactinium is a scarce, radioactive actinide found in trace amounts in uranium ores and primarily of interest for nuclear science.
Properties
It commonly exhibits +5 oxidation state, forms complex oxides and is chemically reactive and radiotoxic.
Occurrence and Uses
No large scale commercial uses exist; protactinium is used in specialized research on actinide chemistry and nuclear properties.
Isotopes and Safety
Protactinium isotopes are highly radioactive and toxic; work with protactinium requires specialized radiological facilities and strict controls.
