Although traces of krypton are found in various minerals, the most important source of krypton is Earth's atmosphere. Air is also the most important source for the other noble gases, with the exception of helium (obtained from natural gas) and radon (obtained as a byproduct of the decay of radioactive elements).nder normal conditions, krypton is a colorless, tasteless, odorless gas. Its density at normal temperature and pressure is about 0.5 oz per gallon (3.7 g per liter), making it nearly three times heavier than air. At extremely low temperatures, krypton may exist as a liquid or a solid.
Krypton is employed alongside other gases to make luminous â neon light â style signs that glow with a greenish-yellow light. Krypton is used as a filling gas for energy-saving fluorescent lights and as an inert filling gas in incandescent bulbs.rypton is considered to be non-toxic. Characteristics: Krypton is a colorless, odorless, inert gas. Although it is extremely unreactive krypton can react with the very reactive gas fluorine. A few compounds of krypton have been prepared, including krypton (II) fluoride and krypton clathrates.
