Gadolinium silih tunggil datu kimia antuk simbolGd miwah wilangan atom 64. Gadolinium punika logam putih maswang pérak ri kala oksidasi kaicalang. Wantah datu tanah langka akedik sané prasida kaprapén miwah ulet. Gadolinium maréaksi sareng oksigén atmospir utawi uap toya sané alon ngawentuk lapisan selem. Gadolinium ring metén Titik Curie saking 20 °C (68 °F) punika féromagnétik, antuk wasa kedeng nuju médan magnét langkung saking nikel. Ring duur suhu punika, Inucap dados datu paramagnétik sané akéh. Wantah ketemuin ring palemahan marupa oksidasi. Ri kala kabelasang, ketah nyané ngelah pangotor saking tanah langka liyanan krana cecirén kimia nyané sané sarupa.
