ALL MOLECULAR GRAPHICS: METALLOIDS (RADIOACTIVE): polonium: atomic arrangement
Polonium: graphic showing the radioactive metalloid with atoms arranged in a simple cubic (primitive cubic) way, with one atom at each corner of a cube. Polonium is the only element like this. This is not close packed and is a strange arrangement. You can find more about this unique packing at the AIP site.
