PHONETICS

IDENTIFICATION

Ytterbium is a soft, malleable and ductile chemical element that displays a bright silvery lustre when in its pure form. It is a rare earth element and it is readily attacked and dissolved by the strong mineral acids. It reacts slowly with cold water and it oxidizes slowly in air. Natural ytterbium is a mixture of seven stable isotopes, which altogether are present at concentrations of 3 parts per million.
