The atomic number of Yttrium is 39 and the atomic mass of Yttrium is 88.9 AMU. Yttrium is in group number 3 and period number 5. Yttrium's electron configuration is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d1. Yttrium is classified as a transition metal. Yttrium has never been found in nature on its own, it has only been found with rare earth metals and some of the uranium ores (Dynamic Periodic). Yttrium is important today because it goes into things like medicines and treatments. Some treatments such as Yttrium Y 90 ibritumomab tiuxetan are used to treat some types of cancers like bone cancers and leukemia. Yttrium was first originally separated from other elements in 1828 when anhydrous Yttrium chloride was heated with Potassium. It was named after a village in Sweden called Ytterby (Dynamic Periodic).
