Xenon is very stable element (inert gas). It can react only with the elements having high electronegative like oxygen and fluorine since bromine is less electronegative it cannot be bonded to xenon. read more
Bromine cause of size comparable to xenon and less electronegativity cannot be accommodated around Xe.thus cannot react.also fluorine react because of its small size and high electronegativity. read more
Bromine is a chemical that is toxic to humans and has a wide range of side effects from contact or ingestion. The use of bromine in industrial applications and manufacturing has exposed some people to unusually high levels. If bromine touches the skin, it can cause lesions and sores that can be very serious. read more
