Strontium was recognized as a new element in 1790 when Adair Crawford analyzed a mineral sample from a lead mine near Strontian, Scotland. Until then scientists had thought strontium and barium were the same element, and only bariumâs existence had been recognized. The mineral took its name from the Scottish town and was called strontianite (strontium carbonate).
Erbium was discovered by Carl G. Mosander in 1842 at Sweden. Origin of name: named after the village of  Ytterby  near Vaxholm in Sweden. In 1842 Gustav Mosander separated yttria, found in the mineral gadolinite, into three fractions which he called yttria, erbia, and terbia.
