Platinum is normally a soft, silvery-white metal that is dence with a sheen to it. Platinum is malleble but not as much as gold. In high heat Platinum does not oxidize in the air and it is unaffected by common acids. Platinum is a mon-dangerous metal but short time exposure to platinum salts can cause irritation around the face area, long time exposure can cause breathing and skin problems.
