Packet 6: Bonus 16

Answer the following about the chemistry of compounds containing krypton and fluorine, for 10 points each.
[10h] The hypervalency of krypton difluoride arises from this type of bonding in which stability arises from resonance between ionic and covalent forms. These bonds show little electron density between atoms and are exemplified by one-one-one propellanes.
ANSWER: charge-shift bonds
[10m] Though not experimentally observed, krypton tetrafluoride is thought to possess the highest known positive value of this quantity. A Latimer diagram shows this quantity for an element as its oxidation state changes.
ANSWER: standard redox potential [accept reduction potential or oxidation potential; accept ORP or Eh; prompt on potential]
[10e] Krypton fluoride acts as the excimer in a type of these devices used for photolithography. These devices can move atoms or nanoparticles in optical tweezing.
ANSWER: lasers [or light amplification by stimulated emission of radiation]
