Frankland Sentence Examples
Frankland had recognized the analogies existing between the chemical properties of nitrogen, phosphorus, arsenic and antimony, noting that they act as trior penta-valent.
Carbon was joined with silicon, zirconium and titanium, while boron, being trivalent, was relegated to another group. A general classification of elements, however, was not realized by Frankland, nor even by Odling, who had also investigated the question from the valency standpoint.
By his own investigations and those of Sir Edward Frankland it was proved that the radical methyl existed in acetic acid; and by the electrolysis of sodium acetate, Kolbe concluded that he had isolated this radical; in this, however, he was wrong, for he really obtained ethane, C 2 H 6, and not methyl, CH 3.
The brilliant researches of Frankland on the organo-metallic compounds, and his consequent doctrine of saturation capacity or valency of elements and radicals, relieved Kolbe's views of all obscurity.
Unable to accept Berzelius's doctrine of the unalterability of organic radicals, he also gave a new interpretation to the meaning of copulae under the influence of his fellow-worker Edward Frankland's conception of definite atomic saturation-capacities, and thus contributed in an important degree to the subsequent establishment of the structure theory.
Frankland introduced the "reflux condenser," i.e.
Thence with much spirit, and in face of many difficulties, he betook himself, with his colleague Edward Frankland, to the university of Marburg (1848-1851), where, by intense application, he obtained his doctorate in two years.
Frankland, when in 1858 Kekule published a paper in which, after giving reasons for regarding carbon as a tetravalent element, he set forth the essential features of his famous doctrine of the linking of atoms. He explained that in substances containing several carbon atoms it must be assumed that some of the affinities of each carbon atom are bound by the affinities of the atoms of other elements contained in the substance, and some by an equal number of the affinities of the other carbon atoms. The simplest case is when two carbon atoms are combined so that one affinity of the one is tied to one affinity of the other; two, therefore, of the affinities of the two atoms are occupied in keeping the two atoms together, and only the remaining six are available for atoms of other elements.
In applied chemistry Frankland's great work was in connexion with water-supply.
Other observations made by Frankland at the time formed the starting-point of a series of experiments which yielded far-reaching results.
AdvertisementFrankland and Lockyer were also the discoverers of helium.
Sir Edward Frankland, who was made a K.C.B.
Armstrong before the London Chemical Society on the 31st of October 1901 contained many personal details of Frankland's life, together with a full discussion of his scientific work; and a volume of Autobiographical Sketches was printed for private circulation in 1902.
For the education of its ministry it supports Manchester College at Oxford (which deduces its ancestry from the academy of Richard Frankland, begun 1670), the Unitarian Home Missionary College (founded in Manchester in 1854 by John Relly Beard, D.D., and William Gaskell), and the Presbyterian College, Carmarthen.
This body met early in 1785, elected Sevier governor of the new state of Franklin (at first Frankland), filled a number of offices, and passed several other acts looking to separate existence.
AdvertisementOn 17th March 1744 a Spanish sloop was taken by Capt. FRANKLAND and carried into Charlestown, S. Carolina.
Frankland showed that any particular element preferentially combined with a definite number (which might vary between certain limits) of other atoms; for example, some atoms always combined with one atom of oxygen, some with two, while with others two atoms entered into combination with one of oxygen.
While the principle of varying valency laid down by Frankland is still retained, Butlerow's view that structure had no spatial significance has been modified.
The structure of the molecule, which mainly followed investigations in organic compounds, Frankland's conception of valency, and finally the periodic law, have alsobeen shown in their chronological order.
