An original Polonium (Po) Atomic Number 84 Periodic Table of Elements Design.
Polonium is a chemical element with symbol Po and atomic number 84. A rare and highly radioactive metal with no stable isotopes polonium is chemically similar to selenium and tellurium though it also shows resemblances to its horizontal neighbors thallium lead and bismuth due to its metallic character. Due to the short half-life of all its isotopes its natural occurrence is limited to tiny traces of the fleeting polonium-210 (with a half-life of 138 days) in uranium ores as it is the penultimate daughter of natural uranium-238.
