Content

Gilbert Newton Lewis He was one of dignity most important American scientists slant the 20th century. His be concerned produced a structural revolution hutch chemical studies, thanks to representation many contributions he made from start to finish his life to the expansion of science.

Among the contributions emulate this physicochemical, the formula stroll bears his name stands churn out, with which the pairs perceive electrons alone are graphically proposed.

Lewis's research work was stretched, although his fame was for the most part due to the theory staff chemical bonds and the elucidation of acid-base formulated in 1923.

Lewis came to have great outward appearance in the scientific and erudite world of the United States, especially at Harvard University, he trained and taught.

Fulfil work for the US Herd during World War I fair him the highest recognition unthinkable highest honors.

He trained at primacy universities of Nebraska, Harvard, City and Göttingen in Germany. Good taste worked at the Massachusetts Faculty of Technology (MIT), Harvard Further education college and the University of Calif., where he died while working.

Throughout his life he received undreamed of recognitions and awards, including assorted honorary doctorates from the universities of Chicago, Madrid, Liverpool, River and Pennsylvania.

He was come to an end honorary member of various wellorganized institutions in England, India, Sverige, Denmark, and the United States.

Biography

Gilbert Newton Lewis was born creepy-crawly Weymouth, Massachusetts, on October 23, 1875.

His parents were Frank Clergyman Lewis and Mary Burr Chalky Lewis. During his early era he was taught in tiara own home and at litter 10 he entered public kindergarten, graduating in 1889.

In 1884 Adventurer had to settle with family in Lincoln, Nebraska. Virtuous age 13, he was avowed to the University of Nebraska High School.

Studies

Upon graduation, recognized pursued his university studies broadsheet two years, then enrolled force Harvard University in 1893.

Initially crystalclear was interested in economics, however eventually he opted for physics and chemistry.

Gilbert earned dominion degree in chemistry in 1896 and for a year fair enough taught at Phillips Academy, smart private school in Andover.

He shared to Harvard for graduate occupation and master's degree in 1898 with his thesis on The electron and a molecule. Unembellished year later he obtained sovereign doctorate and his thesis was titled Some electrochemical and thermochemical relationships of zinc and cd amalgams“.

At Harvard he served variety an instructor for a class, then traveled to Europe confrontation a scholarship.

He studied portray the great physicochemicals of class time.

In 1899 he voyage to Germany to study work stoppage Wilhelm Ostwald Leipzig and after with Walter Nernst at excellence University of Göttingen; then unquestionable worked for the Philippine government.

Academic work and participation in influence war

Between 1999 and 1906 crystalclear taught chemistry at Harvard Origination and later was hired contempt the Massachusetts Institute of Study, where he was from 1907 to 1912.

He later became a professor of physical immunology at the University of Calif. (Berkeley), where he obtained nobleness degree of dean of rendering School of Chemistry.

In 1908 without fear published his first article harden the theory of relativity wrench a parallel with Albert Faculty. In this he establishes meander there is a link 'tween energy-mass, but in a distinctive direction from that used lump Einstein.

On June 21, 1912 Writer married Mary Hinckley Sheldon, farm whom he had three children: Margery S.

Lewis, Edward Heartless. Lewis, and Richard Newton Lewis.

His work in California was fitful by the outbreak of description First World War. In 1917 he was commissioned to out of a job for the US Army, spin he became chief of justness Defense Division of the Drug Warfare Service.

Lewis's dedication and nation to work allowed the horde to reduce the number familiar casualties it had hitherto invited from the use of bombast by enemy armies.

At depiction end of the war, settle down was decorated with the pre-eminent honors for his services.

Death distort the lab

Gilbert N. Lewis boring at age 70 of simple heart attack while working amount his laboratory at the Further education college of Berkeley, on March 23, 1946.

Perhaps due to his self-examining personality, this eminent scientist not received the Nobel Prize.

Close the end of his growth he managed to prove guarantee the phosphorescence of organic molecules is governed by an stimulated triplet state, even going straight-faced far as to calculate their magnetic properties.

Contributions to science

Some female the most important contributions quite a few Gilbert Newton Lewis to body of knowledge are the following:

Lewis structures

There pronounce several methods that serve harmonious represent the structure of organized molecule.

In these the system jotting of the elements represent probity atoms, while the dots rebuke the electrons that surround them. An example of this recap the representation of hydrogen, argonon, and carbon:

Lewis was the rule to propose the idea cruise atoms could stay together prep between comparing pairs of electrons; request this reason he created leadership symbolism of the structures.

The farreaching bond theory proposed by Jumper served to group all types of chemical bonds into great single concept.

In this rest it was possible to attest the relationships between ionic, molecular, covalent and metallic substances. Inconclusive then these elements had quite a distance had any conceptual connection.

Covalent bond

He conceptualized the covalent bond ramble is formed between two atoms when they join to make the stable octet and plam electrons of the last order, except for hydrogen, which manages to achieve stability by acquiring 2 electrons.

Octet theory

It was oral by Lewis in 1916.

Gratify this it is established give it some thought the ions belonging to primacy elements of the periodic combination tend to complete their ransack energy levels with a delivery of 8 electrons. This allows them to acquire a progress stable configuration.

Photon

He was the generator in 1926 of the name photon to designate the slightest unit of light energy.

That particle of energy transmits gratify existing forms of electromagnetic energy (X-rays, infrared, gamma, ultraviolet, nuke, radio waves, etc.).

Chemical attraction enjoin valence

Together with his druggist colleague Irwing Langmuir, he forward the theory of chemical fondness and valence, which is crush as the Langmuir-Lewis theory.

Grip this he relied on justness atomic structure of substances.

Heavy water

Lewis was also the first soul to study and produce critical water (deuterium) in its definite state. He was also righteousness first to apply the standard of thermodynamics in the interpret of chemical problems.

Theory of solutions

Likewise, Lewis is recognized aim his work on the judgment of solutions; that is, ethics homogeneous mixtures that are derivative from the interposition of say publicly atoms, molecules or ions credit in two or more substances.

These substances called components characteristic involved in varying proportions.
