Understanding the element
Xenon (Xe) is chemical element 54. It belongs to the noble gases, and its reference state at room temperature is a gas. 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 lighting, medical imaging equipment and ion propulsion.

What its position in the table tells us
Xenon sits in period 5, group 18 and the P block. That location is useful because neighbouring elements often share trends in valence electrons, oxidation states and bonding behaviour.
Worth remembering
Xenon has a characteristic place in the periodic table that helps explain both its chemistry and its practical uses
