Understanding the element
Antimony (Sb) is chemical element 51. It belongs to the metalloids, 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 flame retardants, alloys and semiconductors.

What its position in the table tells us
Antimony sits in period 5, group 15 and the P block. That location is useful because neighbouring elements often share trends in valence electrons, oxidation states and bonding behaviour.
Worth remembering
Antimony has a characteristic place in the periodic table that helps explain both its chemistry and its practical uses
