Terbium is a chemical element discovered in the middle of the 19th century and named after a small town in Sweden. It is a silvery soft and quire reactive metal which forms its oxide when contacting with air. It occurs in its natural form on our planet and can be extracted from various minerals like euxenites, but it can also be produced artificially. Terbium is not toxic and does not play an important biological role. Terbium is used in compounds with other elements in such industries as electronics, medicine, chemical industry, and so on.
