Terbium silih tunggil datu kimia antuk simbol Tb miwah wilangan atom 65. Punika mawarna putih masawang pérak, logam tanah langka sané prasida kaprapén , ulet , miwah bélék antuk kagetep nganggén tiuk. Anggota kasia saking seka lantanida , terbium punika logam éléktropositif sané maréaksi sareng toya, ngembangang gas hidrogén . Terbium nénten taén katemuin ring palemahan dados datu bébas, menawi makéh ring mineral , rumasuk cérit , gadolinit , monasit , xénotime , miwah éuksénit .
