Wikipedia säger. Polonium is a chemical element with the symbol Po and atomic number 84, discovered in 1898 by Marie Skłodowska-Curie and Pierre Curie.

It is a radioactive, colorless, odorless, tasteless noble gas.It occurs naturally in minute quantities as an intermediate step in the normal radioactive decay chains through which thorium and uranium slowly decay into lead and various other short-lived radioactive elements. Polonium is a chemical element with symbol Po and atomic number 84. Classified as a metalloid, Polonium is a solid at room temperature. Polonium-216 atom is the radioactive isotope of polonium with relative atomic mass 216.001905 and half-life of 0.145 s. Phrases contain similar "polonium atomic number" from credible sources.

Apr 22, 2014 Eric Ansoborlo considers the disproportionate potency of polonium compared with its in this case between the Curies and a number of German scientists French Alternative Energies and Atomic Energy Commission,

The element has 33 radioactive isotopes, including polonium-208 and polonium-210. It is a scarce element that is produced in nuclear reactors. Neurons are used to bombard bismuth-209, and bismuth-210 is formed as a result. Extracting polonium was challenging because there was such a miniscule amount; 1 ton of uranium ore contains only about 100 micrograms (0.0001 grams) of polonium. Nonetheless, the Curies were able Polonium is a chemical element with symbol Po and atomic number 84, discovered in 1898 by Marie Curie and Pierre Curie.
