- from Greek: κρυπτός kryptos "the hidden one"
- a colorless, odorless, tasteless noble gas
- it [...] is useful in photography as a brilliant white light source.
- it is considered to be a non-toxic asphyxiant
- breathing a gas containing 50% krypton and 50% air would cause narcosis [...] and potentially could affect anyone breathing it. Nevertheless, that mixture would contain only 10% oxygen and hypoxia would be a greater concern.
I am officially in love with krypton.
