A rare and highly radioactive element with no stable isotopes, polonium is chemically similar to bismuth and tellurium, and it occurs in uranium ores. Applications of polonium are few. 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 the symbol Po and atomic number 84.

A rare and highly radioactive element with no stable isotopes, polonium is chemically similar to bismuth and tellurium, and it occurs in uranium ores.

Plutonium is a radioactive chemical element with the symbol Pu and atomic number 94. It is an actinide metal of silvery-gray appearance that tarnishes when exposed to air, and forms a dull coating when oxidized. The element normally exhibits six allotropes and four oxidation states. It reacts with carbon, halogens, nitrogen, silicon, and hydrogen. 2020-05-09 · Polonium-210 (the isotope of Polonium with Atomic Weight of 210; since the Atomic Number of Polonium is 84, meaning it has 84 protons and 84 electrons orbiting around its nucleus, we know that it must have 210 - 84 = 126 neutrons) is unstable and emits very weak gamma rays.
