1921 I. Langmuir in Science 22 July 60/2 According to Postulate 1, the first complete layer in any atom consists of two electrons close to the nucleus. Let us call this stable pair of electrons a duplet and let us broaden the definition of duplet to include any pair of electrons which is rendered stable by its proximity to one or more positive charges. We may now state the second postulate... Two atoms may be coupled together by one or more duplets held in common by the completed sheaths of the atoms.
