21 Krypton Difluoride Uses: Facts You Should Know!

Krypton is a noble gas that belongs to the group of elements known as the noble gases. It is a colorless and odorless gas that is present in trace amounts in the Earth’s atmosphere. Krypton is known for its inert nature, which means it does not readily react with other elements or compounds. This property makes it useful in various applications, including lighting, lasers, and as a filling gas in certain types of windows.

What is Krypton?

Krypton, with the chemical symbol Kr and atomic number 36, was discovered in 1898 by Sir William Ramsay and Morris Travers. It is named after the Greek word “kryptos,” which means hidden or concealed. Krypton is one of the rarest elements on Earth, accounting for only about 1 part per million in the atmosphere.

Krypton is a member of the noble gas family, which includes helium, neon, argon, xenon, and radon. These gases are characterized by their low reactivity and stability due to their full outer electron shells. Krypton has a full complement of eight electrons in its outer shell, making it highly stable and unreactive.

Discovery of Krypton and its properties

Krypton was discovered through the process of fractional distillation of liquid air. Ramsay and Travers were able to isolate krypton by cooling and compressing air until it liquefied, then slowly warming it up. As the air warmed, different components started to boil off at different temperatures, allowing the researchers to collect and analyze the gases.

Krypton has several notable properties. It is a colorless and odorless gas with a density greater than air. It is also a poor conductor of heat and electricity. Krypton is known for its characteristic glow when electrically charged, which makes it useful in lighting applications. It is commonly used in fluorescent lamps, high-intensity discharge lamps, and photographic flashes.
