Po.
The element symbol of polonium is Po. It is a radioactive element with atomic number 84.
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.
Polonium with the atomic number 84 is in the group 16 and period 6 of the periodic table of Mendeleev. Some compounds of polonium are: PoO, PoO2, PoO3, PoH2, halides as PoX2, PoX4, PoX6 and the strange class of polonides (compounds of polonium with other metals). The Pauling electronegativity is 2. Possible valences are: 2, 4, 5, 6, -2.
