Holmium is a chemical element with the symbol Ho and atomic number 67.

It is a rare earth element and the 11th element in the lanthanide series.

Discovered in 1878, holmium is a soft, malleable, malleable, silvery rare-earth metal. It has the highest magnetic permeability of all elements, similar to dysprosium. It is also used as a burnable poison in nuclear reactors due to its ability to absorb neutrons.
