Gadolinium | Educational Word Lists and Word Search Games

Gadolinium is a chemical element with the symbol Gd and atomic number 64. Gadolinium is a silvery-white metal when oxidation is removed. It is only slightly malleable and is a ductile rare-earth element. Gadolinium reacts with atmospheric oxygen or moisture slowly to form a black coating. Gadolinium below its Curie point of 20 °C (68 °F) is ferromagnetic, attracting a magnetic field higher than a nickel. Above this temperature, it is the most paramagnetic element. It is found in nature only in an oxidized form. When separated, it usually has impurities of the other rare earth because of their similar chemical properties.
