Name: Polonium

Atomic Symbol and Mass Number: Po [84]

Electron Configuration: [Xe] 6s   4f   5d   6p

Atomic Radii: 168 pm

Electron Affinity: 183.3 kJ/mol

Oxidation States: −2, +2, +3, +4, +6

Electronegativity Value: 2.0

Elemental Group: Metalloid

Uses and Properties:

  • The alpha rays emitted by polonium can be used to eliminate static electricity produced during processes such as rolling paper, wire, and sheet metal.

  • Polonium is also used in anti-static brushes to eliminate dust on photographic film.

  • It is sealed in brushes to control the radioactive emissions.

  • Polonium is a radioactive, extremely rare semi-metal. It is reactive, silvery-gray, it dissolves in dilute acids, but it is only slightly soluble in alkalis.

  • It is fairly volatile: about half of a sample of it will evaporate within 3 days (unless it is kept in a sealed container).
