Itterbium silih tunggil datu kimia antuk simbol Yb miwah wilangan atom 70. Puniki datu kaping pat welas miwah kaping kalih saking untat ring bacakan lantanida, sané marupa dasar tegtegan rélatif saking paindikan oksidasi +2. Menawi, sekadi lantanida liyanan, paindikan oksidasi pinih ketah punika +3, sakancan ring oksida, halida, miwah senyawa liyanan. Ring larutan matoya, sekadi senyawa lantanida ungkur liyanan, senyawa Itterbium larut ngawentuk kompléks sareng sia molekul toya. Mawinan konfigurasi éléktron kulit katutup nyané, kakerepan miwah titik leleh taler titik didih nyané matiosan doh sareng makéhan lantanida liyanan.
