From Hydrogen to Tellurium - Palladium

Palladium , Pd is the 46th element. Like the elements I wrote about for the last couple of weeks, palladium is also in the platinum metals group. It's uses are similar to those of rhodium - a catalyst in catalytic converters, electrical connections and jewellery.Palladium has no known biological role and is not present in the human body.

From Hydrogen to Tellurium - Rhodium

Rhodium Rh at number 45 is another slivery white transition metal. It is also in the platinum group.My research tells me that it is used in alloys, jewellery, In electrical applications and as a catalyst. Rhodium is extracted from ore by industry. It is not present in the human body and though the metal itself is not toxic many rhodium compounds are toxic amdalso cause cancer.
