Krypton is a colorless, odorless, and tasteless inert gas with a concentration of one part per million in the atmosphere. Orange-red during discharge and present in traces in the atmosphere, it can be separated from liquid air by fractional distillation. The multiple spectral lines of krypton give ionized krypton gas discharge tubes a white appearance. As krypton gas injected into light bulbs make them glow white, the gas is often used to make fluorescent lamps. Similar to other inert gases, Krypton has chemical properties which are extremely inactive, making it hard for it to produce chemical interactions with other substances.
