The broad definition, used generally throughout history, is that chemical affinity is that whereby substances enter into or resist decomposition. [ 2 ] The modern term chemical affinity is a somewhat modified variation of its eighteenth-century precursor "elective affinity" or elective attractions, a term that was used by the 18th century ...
"Biophilia" is an innate affinity of life or living systems. The term was first used by Erich Fromm to describe a psychological orientation of being attracted to all that is alive and vital. [ 3 ] Wilson uses the term in a related sense when he suggests that biophilia describes "the connections that human beings subconsciously seek with the ...
Affinity (taxonomy) – mainly in life sciences or natural history – refers to resemblance suggesting a common descent, phylogenetic relationship, or type. [1] The term does, however, have broader application, such as in geology (for example, in descriptive and theoretical works [2] [3]), and similarly in astronomy (for example, see "Centaur object" in the context of 2060 Chiron's close ...
The Goldschmidt classification, [1] [2] developed by Victor Goldschmidt (1888–1947), is a geochemical classification which groups the chemical elements within the Earth according to their preferred host phases into lithophile (rock-loving), siderophile (iron-loving), chalcophile (sulfide ore-loving or chalcogen-loving), and atmophile (gas-loving) or volatile (the element, or a compound in ...

Nature connectedness is the extent to which individuals include nature as part of their identity. [1] It includes an understanding of nature and everything it is made up of, even the parts that are not pleasing. [2]
The electron affinity of molecules is a complicated function of their electronic structure. For instance the electron affinity for benzene is negative, as is that of naphthalene, while those of anthracene, phenanthrene and pyrene are positive. In silico experiments show that the electron affinity of hexacyanobenzene surpasses that of fullerene. [5]
Most siderophile elements have practically no affinity whatsoever for oxygen: indeed, oxides of gold are thermodynamically unstable with respect to the elements. Copper, silver, gold, and the six platinum group metals are the only native metals that occur naturally in relatively large amounts.
