17 Facts About Ytterbium

Ytterbium is a chemical element with the symbol Yb and atomic number 70.

Ytterbium suspected that ytterbia was a compound of a new element that he called "ytterbium" .

Ytterbium is a soft, malleable and ductile chemical element that displays a bright silvery luster when pure.

Ytterbium is quite electropositive, and it reacts slowly with cold water and quite quickly with hot water to form ytterbium hydroxide:.

Ytterbium ion absorbs light in the near infrared range of wavelengths, but not in visible light, so ytterbia, Yb2O3, is white in color and the salts of ytterbium are colorless.
