- The higher the valency of the counterions, the more significant is the reversal of the effective charge of the aggregates.
- Plutonium has five different crystal-type conditions or ‘phases’ that it can be in, and has five possible valencies.
- The degree of flocculation, and hence randomness of particle orientations on sedimentation, generally increases with the concentration and valency of the cations in the solution.
- Depending on the charges of additional groups that may be bound to the phosphate group, phospholipids in water can have a valency between - 2 and + 1, and also neutral groups are possible.
1. 1.1Linguistics The number of grammatical elements with which a particular word, especially a verb, combines in a sentence.
  ‘give’ has a valency of three in ‘I (1) gave it (2) to him (3)’
