Description: Yttrium is a soft, silvery-white metal that is stable in air due to the formation of an oxide film on its surface. It burns if ignited, and is attacked by water and forms hydrogen. Yttrium is used in various ways: to give red colours in TV screens, in X-ray filters, superconductors and for superalloys.
