Ytterbium is a soft, malleable and rather ductile element that exhibits a bright silvery luster. A rare earth, the element is easily attacked and dissolved by mineral acids, slowly reacts with water, and oxidizes in air. The oxide forms a protective layer on the surface. Compounds of ytterbium are rare. #periodictable #allinfobits #lanthanides #fblock #ytterbium
