Valency


Definition:

  • (n.) See Valence.
  • (n.) A unit of combining power; a so-called bond of affinity.

Example Sentences:

  • (1) The mixed-valence-state cytochrome oxidase mixed with O2 at -24 degrees C and flash-photolysed at -60 to -100 degrees C reacts with O2 and initially forms an oxy compound (A2) similar to that formed from the fully reduced state (A1).
