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, making up about 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 several applications in various fields. It is used in lighting, particularly in certain types of high-intensity discharge lamps, where its strong emission lines produce a characteristic white light. Krypton is also used in flash photography, as it produces a bright white light when electrically excited. Additionally, krypton is utilized in certain laser technologies and as a filling gas in certain types of insulation windows.
8. Isotopes: Krypton has several naturally occurring isotopes, including stable isotopes such as krypton-84, krypton-86, krypton-82, and krypton-83. Radioactive isotopes such as krypton-85 are also present in trace amounts in the environment.
9. Medical Applications: Krypton-81m, a radioactive isotope of krypton, is used in nuclear medicine for lung ventilation studies. It can be inhaled and used to image lung airflow and diagnose certain lung conditions.
10. Compounds: Krypton is generally considered to be chemically unreactive and does not form stable compounds under normal conditions. However, it can form weakly bound compounds with highly electronegative elements, such as fluorine and oxygen, under specific conditions.
