Due to Krypton's large number of spectral lines, it's ionized gas is white, which is why light bulbs that are krypton based are used in photography and studio lighting in the film industry.
In neon lights, Krypton reacts with other gases to produce a bright yellow light as well. The isotope 85 Kr can also be used in combination with phosphors to produce materials that shine in the dark due to the fact that this particular isotope of Krypton reflects off of phosphors. Krypton is also used in lasers as a control for a desired wavelength, especially in red lasers because Krypton has a much higher light density in the red spectral region than other gases such as Neon, which is why krypton-based lasers are used to produce red light in laser-light shows.
It is used to distinguish hydrophobic and hydrophillic regions containing an airway. Facts Element number: 36 Electron configuration: [Ar]3d 10 4s 2 4p 6 Atomic weight: Isolation It ranks sixth in abundance in the atmosphere. Applications Krypton gas is used in various kinds of lights, from small bright flashlight bulbs to special strobe lights for airport runways. Perhaps one of the most significant uses of Krypton is in the krypton-fluoride laser which is used in nuclear fusion energy research.
An international agreement was made in to base the length of the meter on the wavelength of light emitted by 86 Kr Problems How is the element Krypton isolated? Why can fluorine react with Krypton to form a compound? What is the electron configuration of Krypton?

Molecule of the Week needs your suggestions! Just above them are helium, neon, and argon. And just below are radon and oganesson. All of these gases are colorless and odorless. Some compounds are only stable in the excited state KrCl, XeF, etc. These exciplexes are formed and break apart repeatedly in excimer lasers.
Xenon will also bind to the protein metmyoglobin, and it acts as an anesthetic when it does. The mostly non-reactive property of krypton and xenon is useful for space propulsion, as it reduces the concern that the expelled propellant will react with the spacecraft.
Both krypton and xenon are found in the atmosphere. In fact, you are breathing some right now. Both are produced by extraction from the air using cryogenic distillation through the same collection process in a roughly 10 to 1 ratio, krypton to xenon. They are found in the atmosphere at that ratio. Krypton is found in air at about 1 ppm and xenon is in the air at less than ppb.
Ignoring the frequent volatility of the krypton and xenon markets and, of course, the laws of supply and demand apply. Compared to other noble gases, krypton and xenon are heavy atoms. Krypton has a mass of 84 amu, and xenon has a mass of amu, which makes xenon the heaviest of all the stable noble gases radon undergoes radioactive decay, with a half-life of less than 4 days. This heavier mass comes into play with sputter deposition.
Argon is most frequently used for sputtering, transferring target atoms to a substrate to create a coating. It is cheap and works best for coating with light target atoms, but a higher yield is obtained when the inert gas has a similar atomic mass to the target atom. Krypton and xenon are used for heavier coatings like titanium.
The mass is also important when etching semiconductor materials. The higher mass of xenon also contributes to making it more efficient to use for electric propulsion of spacecraft.
