What its position in the table tells us
Holmium sits in period 6 and the F block. That location is useful because neighbouring elements often share trends in valence electrons, oxidation states and bonding behaviour.
Worth remembering
Holmium has a characteristic place in the periodic table that helps explain both its chemistry and its practical uses
