-== Discovery ==
-Wollaston discovered it while on Safari in Rhodesia. He was studying local minerals and came across platinum ore. The baked the platinum ore at the equivalent of gas mark 5 (or 300 kelvin) and then proceeded to dissolve it in a solution of Sodium Potassamide.
-When he added Hypochloric acid to this solution, rhodium was formed as a precipitate (changing the previously rosy solution into a bright green color.)
