Yttrium turnings ignite in air. Found in most rare-earth minerals. Moon rocks contain Yttrium.The electron configuration is 2-8-18-9-2. Yttrium has no biological role,but it does have a geological role. It can be a solid or become a metal, but we usually leave it as itself(crystal) or into a powdery substance.
