Ho - Holminm
Atomic Number: 67 Period Number:6 Group Number: None
Holmium is a silvery-white metal, which belongs to lanthanide series. There is less free element found in nature and most of them exist in the minerals monazite, gadolinite, etc. Only one stable isotope of holmium is found in nature: 165Ho.
Holmium has not been widely used until now. Because it has the highest magnetic strength of all the elements, this will make foundation for its future function in magnetic field application.
