39 Y 이트륨 88.906 u

이트륨 개요

Yttrium is a silvery transition metal of atomic number 39 and atomic mass 88.906, a solid under standard conditions with the configuration [Kr] 4d1 5s2 and an electronegativity of 1.22. Positioned in group 3, period 5, it is frequently found together with the rare earth elements and shares many of their properties, so that it is commonly mined and processed alongside them. Yttrium is used in light-emitting diodes and in superconducting materials, and its radioactive isotopes have applications in cancer treatment. Its chemistry is dominated by the stable, triply charged ion, a single oxidation state that distinguishes it from many later transition metals.
