Krypton

Krypton is a chemical element with the symbol Kr and atomic number 36. It is a noble gas, meaning it is inert and unlikely to react with other elements. Krypton is colorless, odorless, and naturally occurring in trace amounts in the Earth's atmosphere. It is used in specialized lighting, such as bright flashlights and certain types of fluorescent lamps, due to its ability to emit a distinctive greenish glow when electrified. Krypton’s stable atomic structure and inertness make it valuable in applications requiring non-reactive gases, including in scientific research and laser technology.
