Bismuth Bi and polonium Po both have an average Atomic Mass of 209 amu
Polonium is a metal element. Atomic mass of it is 209.
The number -209 indicates the atomic mass of the specific isotope of polonium known as Polonium-209. This isotope of polonium has 209 nucleons (protons and neutrons) in its nucleus, giving it an atomic mass of 209 atomic mass units.
Each of the 33 isotopes of polonium has a specific atomic mass; because all the isotopes are unstable is difficult to give an atomic weight for the element. See the link.
The atomic number of polonium is 84.The atomic weight of Po is 209 grams per mole.See the Web Links to the left of this answer for a periodic table with more information about this element!
