Understanding the element
Strontium (Sr) is chemical element 38. It belongs to the alkaline-earth 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 fireworks, magnets and medical applications.

What its position in the table tells us
Strontium sits in period 5, group 2 and the S block. That location is useful because neighbouring elements often share trends in valence electrons, oxidation states and bonding behaviour.
Worth remembering
Strontium has a characteristic place in the periodic table that helps explain both its chemistry and its practical uses
