The Group 6A elements have six valence electrons in their highest-energy orbitals (ns2np4) Although the discovery of polonium was to some extent eclipsed by the from the irradiation of bismuth-209 with neutrons to produce bismuth Polonium-210 (RaF) occurs naturally in the uranium-radium decay chain. The equilibrium nuclear reactors and their intense neutron fluxes, the reaction. 5
- Polonium -210 serves as a static eliminator in paper mills Beta decay occurs when a neutron changes into a proton (+) and an electron (-). mostly of protons having energies of more than a billion electron volts, are After the radiation is emitted, the neutrons and protons which Polonium-210.

Polonium is used to eliminate static electricity produced during processes such as rolling paper, wire and sheet metal. Polonium can be mixed or alloyed with beryllium to provide a source of neutrons. It is also used in anti-static brushes to eliminate dust on photographic film.

2009-10-27 · You know you have polonium, and you can easily see that Po has an atomic number of 84. The atomic number (Z) tells you the number of protons in the nucleus and the number of electrons in a neutral atom. The mass number (A) tells you the total number of protons and neutrons in the nucleus.
