Etymology: Holmium takes its name from Stockholm, the Swedish city where Per Teodor Cleve, one of its discoverers, was based. The Latin name "Holmia" was the classical form used for the city, and chemists in the period often gave new elements Latinized place names or classical allusions. Cleve's work on rare earth minerals led him to isolate the element, and the name recorded his home city in the periodic table. The city's name itself reflects its island geography. "Holmia" draws on the Swedish word "holm," meaning a small island, a fitting root for a city built across several islands where Lake Mälaren meets the Baltic Sea. The element therefore carries a geographic memory several steps removed from the metal it names.
