- [Properties]
-
- Krypton is characterized as a dense, colorless, odorless, and tasteless
- gas. Its naturally occurring, nonradioacitve isotopes are completely
- harmless to life forms.
- The Group-0, noble gasses (now sometimes called Group VIIIA) were thought
- to be totally inert until 1967. At that time, chemists began finding ways
- to get these so-called inert elements to combine with others. Today
- krypton fluoride is not exactly a common household chemical, but it is a
- prototype for producing similar compounds of krypton and other noble gasses
- that are called clathrates.
