Understanding the element
Praseodymium (Pr) is chemical element 59. It belongs to the lanthanoids, and its reference state at room temperature is a solid. Those basic facts are a useful starting point for its chemistry and applications.
Where do we encounter it?
In practice, it turns up most often in magnets, aircraft alloys and special glasses.

What its position in the table tells us
Praseodymium 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
Praseodymium has a characteristic place in the periodic table that helps explain both its chemistry and its practical uses
