n. a rare-earth, trivalent element found in gadolinite. Symbol: Ho; at. wt.: 164.930; at. no.: 67. [1879; < New Latin, Medieval Latin Holm(ia) Stockholm (near where gadolinite and other rare-earth minerals are found) + -ium²]

hol·mi·um

(hōl′mē-əm) Symbol Ho A soft, silvery, easily shaped metallic element of the lanthanide series. When exposed to a magnetic field, holmium becomes highly magnetic. It is mainly used in scientific research but has also been used to make electronic devices. Atomic number 67. See Periodic Table.

The metal was discovered spectroscopically in 1878 by the Swiss chemists Soret and Delafontaine and independently in 1879 by the Swedish chemist Per T. Cleve; it is named for Cleve's native city.
