One of the lanthanides, ytterbium is a chemical element discovered by a Swiss scientist and named after a small town in Sweden, Ytterby. It is a soft metal of dark grey color, and it is quite a rare element on our planet. It can be obtained from a number of minerals like monazites, gadolinites, xenomites, and others. Ytterbium is not toxic and does not exist in living organisms on our planet. Ytterbium is used in alloys with other metals to produce strong steels for various parts of electronic devices, etc. It also has applications in laser producing.
