In chemical physics and physical chemistry, chemical affinity is the electronic property by which dissimilar chemical species are capable of forming chemical compounds. [1] Chemical affinity can also refer to the tendency of an atom or compound to combine by chemical reaction with atoms or compounds of unlike composition.
Affinity, the UK's first road-legal solar car, built by Cambridge University Eco Racing; Affinity (mathematics), an affine transformation preserving collinearity; Affinity (pharmacology), a characterisation of protein-ligand binding strength; Affinity (sociology), a shared interest and commitment between persons in groups and/or willingness to ...
In law and in cultural anthropology, affinity is the kinship relationship created or that exists between two people as a result of someone's marriage. It is the relationship each party in the marriage has to the family of the other party in the marriage.
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]
The higher the proton affinity, the stronger the base and the weaker the conjugate acid in the gas phase.The (reportedly) strongest known base is the ortho-diethynylbenzene dianion (E pa = 1843 kJ/mol), [3] followed by the methanide anion (E pa = 1743 kJ/mol) and the hydride ion (E pa = 1675 kJ/mol), [4] making methane the weakest proton acid [5] in the gas phase, followed by dihydrogen.
Affinity bias, also known as the similarity bias, similar-to-me effect, and the mini-me syndrome, refers to an implicit cognitive bias where people are favorably ...
Affinity in terms of sociology, refers to "kinship of spirit", interest and other interpersonal commonalities. Affinity is characterized by high levels of intimacy and sharing, usually in close groups, also known as affinity groups. It differs from affinity in law and Catholic canon law which generally refer to the marriage relationship.
The Fourth Lateran Council removed the second type of affinity rule and the new axiom became: "affinity does not beget affinity", which is the principle followed in the modern Catholic Church. [8] It also limited both affinity and consanguinity prohibitions to the fourth degree, but retained the same method of calculating, counting back to a ...
