Chemistry of Krypton
Krypton, a noble gas, is a chemical element with the symbol Kr and atomic number 36. It was discovered in 1898 by Sir William Ramsay and Morris Travers, who were studying the residue left after evaporating liquid air.
They observed a new component that emitted a distinct yellow-green light when an electric current was passed through it. This unique property led to the naming of the element after the Greek word “kryptos,” meaning hidden or concealed.
Discovery and History
The discovery of krypton was a significant milestone in the field of chemistry. Ramsay and Travers were able to isolate krypton by fractional distillation of liquid air, a process that involves cooling air until it liquefies and then gradually warming it up to separate its components based on their boiling points.
This groundbreaking technique allowed them to identify and isolate several noble gases, including krypton.
Krypton’s existence had been predicted by chemist Henry Cavendish in the late 18th century, who theorized the presence of an unknown gas in the atmosphere. However, it wasn’t until Ramsay and Travers’ experiments that krypton was officially discovered and characterized.
Basic Chemistry
Krypton is a colorless, odorless, and tasteless gas that is part of the noble gas group on the periodic table. It is chemically inert, meaning it does not readily react with other elements or compounds.
This inertness is due to its stable electron configuration, with a full outer shell of eight electrons. As a result, krypton does not form compounds under normal conditions and is considered to be non-reactive.
Krypton is present in trace amounts in the Earth’s atmosphere, making up about 1 part per million. It is obtained commercially through the fractional distillation of liquid air or by cryogenic separation techniques.
Due to its low reactivity, krypton finds limited applications in various fields, such as lighting, lasers, and as a filling gas in certain types of insulation.
Interesting Physical Properties of Krypton

Krypton is a noble gas that is colorless and odorless in its natural state. This property makes it difficult to detect without specialized equipment. It is often used in lighting applications, such as fluorescent lamps, where its lack of color allows for a clear and bright light source.
2. High Density
Krypton has a high density compared to other gases, making it heavier than air. This property allows it to be used in certain applications where its density is advantageous, such as in the production of insulating glass windows. The high density of krypton helps to reduce heat transfer and improve energy efficiency.
3. Low Boiling and Melting Points
Krypton has relatively low boiling and melting points compared to other elements. It boils at -153.22°C (-243.8°F) and melts at -157.36°C (-251.3°F). These low temperatures make krypton useful in cryogenic applications, such as cooling superconducting magnets and preserving biological samples.
4. Non-reactive and Stable
Krypton is a non-reactive gas, meaning it does not readily react with other elements or compounds. It is considered to be chemically inert, making it a stable element. This property allows krypton to be used in various applications, including as a filling gas in incandescent bulbs to prevent the filament from oxidizing.
5. High Thermal Conductivity
Krypton exhibits high thermal conductivity, which means it can efficiently transfer heat. This property makes it useful in certain industrial processes, such as in the production of lasers and plasma displays. The high thermal conductivity of krypton allows for effective heat dissipation, ensuring the proper functioning of these devices.
