A silvery metallic element of the lanthanide
series, symbol Ho, atomic number 67, atomic
weight 164.93. It occurs in combination with
other rare-earths and in various minerals
such as gadolinite. Its compounds are highly
magnetic. The element was discovered
spectroscopically in 1878 by Swiss chemists L
Soret and Delafontaine and independently in
1879 by Swedish chemist P T Cleve
(1840-1905), who named it for Holmia, Latin
for Stockholm (near where it was found).
