It is for the indication of its Atomic Mass usually it is written at the superscript of its symbol Po as 84Po209
209Po and 211Po are isotopes of polonium. 209Po and 211Po have the same number of protons and electrons, also the same atomic number; the number of protons is of course different. The two isotopes are radioactive.
The standard atomic weight of polonium is [210], after IUPAC rules.
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!
Polonium is a metal element. Atomic mass of it is 209.
Now polonium is not extracted from uranium ores; polonium is more simple prepared by nuclear reactions.
Polonium is a metal element. Atomic mass of it is 209.
84 protons, 84 electrons and 136 neutrons.
209Po and 211Po are isotopes of polonium. 209Po and 211Po have the same number of protons and electrons, also the same atomic number; the number of protons is of course different. The two isotopes are radioactive.
Polonium has 84 protons and electrons; the number of neutrons is different for each isotope: Number of neutrons = Atomic mass of an isotope - Atomic number of polonium (84)

Polonium is a metal element. Atomic mass of it is 209.
Po is the symbol for polonium. It was discovered by polish Chemist and Physicist Marie Curie in 1898, and she named the element in honor of her country. It has an atomic number and atomic mass of 84 and 209 u respectively.
The most used nuclear reaction to obtain polonium is:Bi-209 + n------------Bi-210----------Po-210
The most common reaction to obtain polonium is;Bi-209 + n------------Bi-210-----------------Po-210 + e-
Now polonium is not extracted from uranium ores; polonium is more simple prepared by nuclear reactions.
