Krypton, periodic table Kr, is a noble gas, much like xenon and argon. It is useful as propellant for ion drives, and an isotope of krypton, 79Kr, has been proposed as a positron source in an experimental radioisotope positron propulsion system. Krypton is also used by SpaceX for the thrusters in its Constellation project. The cost of Krypton is about 0,5$ per liter or about 350$ per kg[1].
