CHEMISTRY GLOSSARY

Holmium was discovered by Per Theodore Cleve (Sweden) in 1879. The origin of the name comes from the Greek word Holmia meaning Stockholm. It is fairly soft, malleable, lustrous, silvery metal. Reacts slowly with oxygen and water. Dissolves in acids. Can react violently with air or halogens. Holmium occurs in gadolinite. Most often from monazite sand. It has very few practical applications; however, it has some unusual magnetic properties that offer some hope for future applications.
