Characteristic

Holmium is a chemical element with the symbol Ho and atomic number 67. Part of the lanthanide series, holmium is a rare-earth element.




Phase at STP： solid

Melting point： 1734 K (1461 °C, 2662 °F)

Boiling point： 2873 K (2600 °C, 4712 °F)

Density (near r.t.)： 8.79 g/cm3

when liquid (at m.p.)： 8.34 g/cm3

Heat of fusion： 17.0 kJ/mol

Heat of vaporization： 251 kJ/mol
