[49] Being lipophilic, krypton has a significant anaesthetic effect (although the mechanism of this phenomenon is still not fully clear,[50] there is good evidence that the two properties are mechanistically related), with narcotic potency seven times greater than air, and breathing an atmosphere of 50% krypton and 50% natural air (as might happen in the locality of a leak) causes narcosis in humans similar to breathing air at four times atmospheric pressure. Consider the element with the electron configuration [Kr]5s24d7. All the noble gases are present in Earths atmosphere and, except for helium and radon, their major commercial source is the air, from which they are obtained by liquefaction and fractional distillation. For chemistry students and teachers: The tabular chart on the right is arranged by boiling point. Thats called a noble gas. Hence, their chemical properties are similar. - Ionization energy. Their electronic structures and the finding that some of them do indeed form compounds has led to the more appropriate designation, Group 18. Krypton produces much higher light power than neon in the red spectral line region, and for this reason, red lasers for high-power laser light-shows are often krypton lasers with mirrors that select the red spectral line for laser amplification and emission, rather than the more familiar helium-neon variety, which could not achieve the same multi-watt outputs.
