Rhodium silih tunggil datu kimia antuk simbol Rh miwah wilangan atom 45. Punika langka, mawarna putih masawang pérak, katos, tahan korosi, miwah mawit kimiawi lembam rumasuk logam transisi. Ipun dados logam mulia miwah anggota saking seka platinum. Wantah kawéntenan asiki isotop ring palemahan, ¹⁰³Rh. Rhodium alami ketah nyané katemuin manados logam bébas, dados paduan sareng logam sarupa, miwah kapah manados senyawa kimia ring mineral sekadi bowieite miwah rhodplumsite. Punika dados silih tunggil logam mulia pinih langka miwah pinih maharga.
