Chemical affinity
In chemistry, chemical affinity is the force of attraction between atoms that keeps them in combination in a molecule as well as the force of attraction between molecules, such as those of biological significance. [1]
Examples
The atoms of a given element may have a greater affinity for the atoms of one element than for another, e.g. hydrogen H has a great affinity for chlorine Cl, with which it easily and rapidly combines to form hydrogen chloride, but has little or no affinity for argon. The affinity between an enzyme and a substrate molecule is another example. A very complex example is the affinity between two human molecules, such as was outlined in German polymath Johann von Goethe's 1809 scientific novella Elective Affinities.
