Krypton relative atomic mass
WebA total of 32 isotopes of krypton have been identified, having atomic masses ranging from 69 to 100. Six of these are stable. The fission product krypton-85 is a beta-emitter having a half-life of 10.72 years. Because it is chemically inert, krypton is difficult to separate from process streams. WebAtomic radius / pm: 202.
