|Left: a human molecular orbital view of the start reaction of the formation of the typical nuclear family at the day of first meeting of two human molecules, e.g. in their school orbitals, symbol S, say at about age 21, from American electrochemical engineer Libb Thims' 2007 Human Chemistry; right: an drawing of semi-orbital / semi-Venn diagram / semi-human chemical bond aspect of the self-visualized existence of a person named Paul, from American psychologist Ruthellen Josselson's 1996 book The Space Between Us. |
|The typical generic idea or conception of the nuclear family: one child and two parents.|
“The nuclear family is a social group characterized by common residence, economic cooperation, and reproduction. It includes adults of both sexes, at least two of whom maintain a socially approved sexual relationship, ...”American electrochemical engineer Libb Thims' 2007 Human Chemistry textbook was the first to depict the so-called 2.5 child nuclear family in human molecular orbital theory terms.
