For our updated Palladium video, we are mining the Royal Society archives for the story of its discovery - a tale of money, an asteroid and stolen samples? The discovery was made by William Hyde Wollaston. Royal Society (Romantic Chemistry Exhibition until June 14): http://royalsociety.org/events/2012/romantic-chemistry/ This video features Professor Martyn Poliakoff.

Palladium is a chemical element with symbol Pd and atomic number 46. It is a rare and lustrous silvery-white metal discovered in 1803 by William Hyde Wollaston. He named it after the asteroid Pallas, which was itself named after the epithet of the Greek goddess Athena, acquired by her when she slew Pallas. Palladium, platinum, rhodium, ruthenium, iridium and osmium form a group of elements referred to as the platinum group metals. These have similar chemical properties, but palladium has the lowest melting point and is the least dense of them.

Every time I see a commercial for a new cell phone, I feel a bit nauseous. I love a new cell phone just like the next person, but because of my training as a materials scientist, I feel like a worker in a sausage factory. Cell phones, like sausages, may be great, but you don’t really want to know what it takes to make them.
