What are the three most common isotopes in polonium?
What are the most common forms of polonium when used by humans?
Asked in Mining
Where would I find a polonium mine?
You cannot mine polonium as the longest lived isotope, polonium-209 has a halflife of only 100 years and most isotopes of polonium have halflives measured in seconds to minutes. Traces of polonium can be found in any uranium ore as it is a daughter of uranium decay. Usable amounts of polonium are manufactured using nuclear reactors.

What are the three naturally occurring isotopes of hydrogen?
Asked in Chemistry, Atoms and Atomic Structure
Are all atoms of a particular element identical?
No, all elements have so called isotopes, meaning that the number of neutrons in the nucleus differs from the most common isotope. Hydrogen, for example, has three known isotopes: 11H, 12H, 13H, where the first one is the most common. They solely in their number of neutrons, not protons. The last two isotopes are less stable, hence less common.
