Polonium is an extremely rare chemical element, accompanying uranium ores; approx. 100 micrograms of polonium in one to (t) of uranium ore.
It accounts ofr 0.934% by volume, of the earth's atmosphere.
Polonium is a radioactive element that occurs naturally in the Earth's crust as a result of the decay of uranium. It can also be artificially produced in nuclear reactors or by bombarding bismuth with neutrons.
Two polonium oxides are known: PoO2 and PoO3.
If you think to the chemical symbol of polonium this is Po.
The valences of polonium are 2, 4 and 6.
Like all metals polonium is a conductor of heat and electricity.
Polonium is a member of the group 16 of the periodic table of Mendeleev (chalcogens).
Protactinium is so scarce that the abundance in the Earth crust was not determined.

Yes, polonium is a naturally occurring element found in trace amounts in uranium ores. However, its synthetic isotopes are also produced in nuclear reactors for various scientific and industrial applications.

The word "abundance" is a noun. An example of a sentence using the word would be: There was an abundance of food being served by waiters.
The Earth's atmosphere has 21% oxygen
Because the interior of the earth is hot.
Earth is the only planet in our solar system with an abundance of liquid water on its surface. Other planets may have water in the form of ice or vapor, but not in liquid form like Earth.
