Facts about the
Definition of the Element Holmium
The Element Holmium is defined as...
A relatively soft, malleable, stable rare-earth element occurring
in gadolinite, monazite, and other rare-earth minerals. The most common uses of Holmium are
in Nuclear reactors.
Interesting Facts
about the Origin and Meaning of the element name Holmium
What are the origins of the word Holmium ?
The name originates from the Latin word Holmia meaning Stockholm.
Facts about the
Classification of the Element Holmium
Holmium classified as an element in the Lanthanide series as one
of the "Rare Earth Elements" which can located in Group 3 elements
of the Periodic Table and in the 6th and 7th periods. The Rare
Earth Elements are divided into the Lanthanide and Actinide
series. The elements in the Lanthanide series closely resemble
lanthanum, and one another, in their chemical and physical
properties. Their compounds are used as catalysts in the
production of petroleum and synthetic products.

Soret in 1878. Per Teodor Cleve independently discovered the
element in 1878.

Facts and Info about
the element Argon - IUPAC and the Modern Standardised Periodic Table
The Standardised Periodic Table in use today was agreed by the
International Union of Pure Applied Chemistry, IUPAC, in 1985
which includes the Holmium element. The famous Russian Scientist,
Dimitri Mendeleev, perceived the correct classification method of
"the periodic table" for the 65 elements which were known in his
time. Holmium was discovered by Marc Delafontaine and Jacques
Louis Soret in 1878. Per Teodor Cleve independently discovered the
element in 1878. The Standardised Periodic Table now recognises more periods
and elements than Dimitri Mendeleev knew in his day but still all
fitting into his concept of the "Periodic Table" in which
Holmium is
just one element that can be found.
