What are 3 things Krypton is used for?
Uses and properties It does not react with anything except fluorine gas. Krypton is used commercially as a filling gas for energy-saving fluorescent lights. It is also used in some flash lamps used for high-speed photography. Unlike the lighter gases in its group, it is reactive enough to form some chemical compounds.

Can krypton burn?
Since it doesn’t combine with other elements, it doesn’t take part in chemical reactions, so it will not burn, cause corrosion, or do other chemical-like things. It is, however, possible for krypton to hurt you. This isn’t because the krypton is poisonous, but because of the lack of oxygen in the room.
