ytterbium
A chemical element with the symbol Yb and atomic number 70, which is a silvery-white rare earth metal.
Noun
Ytterbium is a rare earth element belonging to the lanthanide series. In scientific discourse, it is characterized by its high reactivity and its specific role in precision physics, particularly in the development of optical lattice clocks which are among the most accurate timekeeping devices ever created.
As a chemical element, it is treated as an uncountable mass noun. It refers to the substance itself rather than individual atoms or discrete objects, meaning it does not typically take a plural form in standard chemical or technical contexts.
Meanings
Examples
Ytterbium lasers are essential for high power industrial cutting.
Business
