Understanding the element
Rhenium (Re) is chemical element 75. It belongs to the transition metals, 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 jet engines, catalysts and thermocouples.

What its position in the table tells us
Rhenium sits in period 6, group 7 and the D block. That location is useful because neighbouring elements often share trends in valence electrons, oxidation states and bonding behaviour.
Worth remembering
Rhenium has a characteristic place in the periodic table that helps explain both its chemistry and its practical uses
