Faraday Society
The Faraday Society was a British society for the study of physical chemistry, founded in 1903 and named in honour of Michael Faraday. In 1980, it merged with several similar organisations, including the Chemical Society, the Royal Institute of Chemistry, and the Society for Analytical Chemistry to form the Royal Society of Chemistry which is both a learned society and a professional body. At that time, the Faraday Division became one of six units within the Royal Society of Chemistry. The Faraday Society published ''Faraday Transactions'' from 1905 to 1971, when the Royal Society of Chemistry took over the publication. Of particular note were the conferences called ''Faraday Discussions'', which were published under the same name. The publication includes the discussion of the paper as well as the paper itself. At the meeting, more time is given to the discussion than to the author presenting the paper as the audience are given the papers prior to the meeting. These conferences co ...

Athenaeum Club, London
The Athenaeum is a private members' club in London, founded in 1824. It is primarily a club for men and women with intellectual interests, and particularly (but not exclusively) for those who have attained some distinction in science, engineering, literature or the arts. Humphry Davy and Michael Faraday were the first chairman and secretary and 51 Nobel Laureates have been members. The clubhouse is located at 107 Pall Mall at the corner of Waterloo Place. It was designed by Decimus Burton in the Neoclassical style, and built by the company of Decimus's father, James Burton, the pre-eminent London property developer. Decimus was described by architectural scholar Guy Williams as "the designer and prime member of the Athenaeum, one of London's grandest gentlemens' sic.html"_;"title="'sic">'sic''clubs".

Linnett Double-quartet Theory
Linnett double-quartet theory (LDQ) is a method of describing the Covalent bond, bonding in molecules which involves separating the electrons depending on their Electron spin, spin, placing them into separate 'spin tetrahedra' to minimise the Pauli repulsions between electrons of the same spin. Introduced by J. W. Linnett in his 1961 monograph and 1964 book, this method expands on the Lewis structure, electron dot structures pioneered by Gilbert N. Lewis, G. N. Lewis. While the theory retains the requirement for fulfilling the octet rule, it dispenses with the need to force electrons into Electron pair, coincident pairs. Instead, the theory stipulates that the four electrons of a given spin should Coulombic force, maximise the distances between each other, resulting in a net tetrahedral electronic arrangement that is the fundamental molecular building block of the theory. By taking cognisance of both the Electric charge, charge and the spin of the electrons, the theory can describe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Valency (chemistry)
In chemistry, the valence (US spelling) or valency (British spelling) of an element is the measure of its combining capacity with other atoms when it forms chemical compounds or molecules. Description The combining capacity, or affinity of an atom of a given element is determined by the number of hydrogen atoms that it combines with. In methane, carbon has a valence of 4; in ammonia, nitrogen has a valence of 3; in water, oxygen has a valence of 2; and in hydrogen chloride, chlorine has a valence of 1. Chlorine, as it has a valence of one, can be substituted for hydrogen. Phosphorus has a valence of 5 in phosphorus pentachloride, . Valence diagrams of a compound represent the connectivity of the elements, with lines drawn between two elements, sometimes called bonds, representing a saturated valency for each element. The two tables below show some examples of different compounds, their valence diagrams, and the valences for each element of the compound. Modern definitions ...
