Product Description

Krypton is a chemical element with the symbol Kr and atomic number 36. Here are some key points about krypton:

1. Chemical Symbol: Kr
2. Atomic Number: 36
3. Atomic Weight: 83.798 atomic mass units
4. State at Room Temperature: Krypton is a colorless, odorless, and tasteless gas. It belongs to the group of noble gases in the periodic table.
5. Noble Gas: Like other noble gases, krypton is chemically inert and does not readily react with other elements. It has a full outer electron shell, making it stable and unreactive under normal conditions.
6. Occurrence: Krypton is a rare gas found in trace amounts in the Earth's atmosphere, estimated to be around 1 part per million by volume. It is obtained as a byproduct of the separation of air during the production of liquid oxygen and nitrogen.
7. Uses: Krypton has a few specialized applications. It is used in certain types of lighting, such as krypton-filled incandescent lamps and fluorescent lamps, where it produces a distinctive white or bluish-white light. Krypton is also used in some laser applications and as a filling gas in certain types of plasma displays.
8. Isotopes: Krypton has several stable isotopes, including krypton-84, krypton-86, krypton-82, and krypton-83. These isotopes have different atomic masses but similar chemical properties.
9. Nuclear Applications: Krypton-85, a radioactive isotope of krypton, is used in various nuclear applications. It is used as a tracer in environmental studies to determine air circulation patterns and in leak detection for sealed systems.
10. Compounds: Krypton is generally unreactive and does not readily form compounds under normal conditions. However, under extreme conditions, such as high pressures or low temperatures, krypton can form compounds with highly electronegative elements like fluorine and oxygen. Examples include krypton difluoride (KrF2) and krypton oxides (KrO and KrO3).
