  Edward Frankland Summary
Frankland's concept of valence was crucial in the later development of structural theory and structural formula s, the attempts to show how atoms are physically connected to each other in molecules.
Frankland was knighted in 1897 and died while on vacation in Norway on August 9, 1899.
One of the purposes of the expedition was to discover whether the rate of combustion of a candle varies with the density of the atmosphere in which it is burnt, a question which was answered in the negative.

 Chemical Bonding Concept/Skills Development
Edward Frankland(1825 - 1899) Frankland developed a theory of valence following research into the properties of zinc methyl, a new reactive organometallic compound, and a series of alkyl-conjugated metals which had different combining powers than the metals alone.
On May 10, 1852, Frankland published an article describing the fixed combining powers of elements which he termed `atomicity.' This term was renamed valence.
Frankland's work on valence, along with an international agreement on atomic weight values signed shortly thereafter united various theoretical schools of chemists into the field of structural chemistry.

FRANKLAND, SIR EDWARD [Frankland, Sir Edward] 1825-99, English chemist.
He made studies of water purification; of flame and luminosity with John Tyndall; of gases with J. Lockyer, with whom he discovered helium; and of the chemistry of foods.
His work on water purification was continued by his son, Percy Faraday Frankland, 1858-1946, also a chemist, who with his wife, Grace Toynbee Frankland, conducted bacteriological studies.

Frankland was a main participant in these developments, and he quickly had company; chemists from Germany, France, England, and Russia were attracted into this new area on the borderline of organic and inorganic chemistry.
Edward Frankland was born on January 18, 1825, in Lancashire, England, the illegitimate son of a distinguished lawyer.
Frankland served as president of the Chemical Society (1871-1873) and was the founding president of the Institute of Chemistry in 1877.

In 1852, Edward Frankland applied the notion of equivalency to the atoms of elements, that is, homogeneous substances which have not been separated into unlike parts.
He arranged the elements in groups, the atoms of those in any one group being of equal value in exchange, inasmuch as each of these atoms combines with the same number of other atoms to form molecules.
When Frankland’s conception had been developed, and the method of determining the equivalency of atoms made more definite and more workable, a vast new field of enquiry was opened, a field which has proved remarkably fruitful both in purely scientific work, and in applied chemistry.

Faraday and my great grandfather, Edward Frankland, an eminent scientist who discovered valency, (the principle ruling the combining powers of chemical elements), were friends and hence Faraday became my grandfather's Godfather.
My father, Edward Percy Frankland, a lecturer in Chemistry at Birmingham University, was, at the time of the acquisition of the farm, a bachelor living at home with his parents and therefore took an active part in the whole project.
Once the Franklands were established at Needlehouse, they soon became friends with the Metcalfe-Gibsons of Coldbeck House in Ravenstonedale and in 1915 my father married the second daughter, Maud, who became my mother.

Edward first synthesised organo zinc compounds by treating organo halides with zinc metal.
From these discovery's the term "Organometallic" was coined for compounds containing direct carbon-metal bonds and Frankland realised the importance of the valency of elements(combining power).
