- Protactinium is a
chemical element in the periodic table that has the symbol Pa and atomic
number is 91 and it is a malleable, shiny, silver-gray radioactive metal
that does not tarnish rapidly in air.
- It is harmful due to its
radioactivity and is also toxic and it is one of the rarest and most
expensive naturally occurring elements.
- A short-lived radioactive
metallic element formed from uranium and disintegrating into actinium
and then into Lead.
- Protactinium occurs in
vanishingly small quantities in the natural decay chains of uranium and
thorium minerals.
- Most of the protactinium is
sourced from thorium that is present in nuclear reactors.
- Possibilities of using
protactinium as a tracer in the fields of geology and pale oceanography
have surfaced recently.
- Protactinium is widely
distributed in very small amounts in the earth’s crust,
and it is one
of the rarest and most expensive naturally occurring elements.
- It does not used for
industrial or commercial uses due to its scarcity, expense, and radio
toxicity and it only used for scientific research activities.
