Gilbert Newton Lewis ForMemRS [ 1] (October 23 [ 2][ 3][ 4] or October 25, 1875 – March 23, 1946) [ 1][ 5][ 6] was an American physical chemist and a dean of the college of chemistry at University of California, Berkeley. [ 3][ 7] Lewis was best known for his discovery of the covalent bond and his concept of electron pairs; his Lewis dot ...
The Lewis structure was named after Gilbert N. Lewis, who introduced it in his 1916 article The Atom and the Molecule. [4] Lewis structures extend the concept of the electron dot diagram by adding lines between atoms to represent shared pairs in a chemical bond. Lewis structures show each atom and its position in the structure of the molecule ...
MO diagram depicting the formation of a dative covalent bond between two atoms. The concept originated with Gilbert N. Lewis who studied chemical bonding. In 1923, Lewis wrote An acid substance is one which can employ an electron lone pair from another molecule in completing the stable group of one of its own atoms.
G. N. Lewis and the Chemical Bond. Pauling, Linus. Journal of Chemical Education, v61 n3 p201-03 Mar 1984. Discusses the contributions of G. N. Lewis to chemistry, focusing on his formulation of the basic principle of the chemical bond--the idea that the chemical bond consists of a pair of electrons held jointly by two atoms. (JN)
Cubical atom. The cubical atom was an early atomic model in which electrons were positioned at the eight corners of a cube in a non-polar atom or molecule. This theory was developed in 1902 by Gilbert N. Lewis and published in 1916 in the article "The Atom and the Molecule" and used to account for the phenomenon of valency. [1]
These theories are: the Valence Bond Theory, the Valence Shell Electron Pair Repulsion (VSEPR), the Ligand Close-Packing (LCP) Model, and the Molecular Orbital Theory (MOT). Explaining the same structure with many theories can cause students to experience confusion and misunderstanding in these subjects (Hurst, 2002).
Because Lewis structures provide a direct connection between molecular structure and properties, the ability to construct and use them is an integral component of many chemistry courses. Although a great deal of time and effort has been dedicated to development of "foolproof" rules, students still have problems with the skill.
the structure of matter (Harrison & Treagust, 2003; Merritt et al., 2007). Structure of matter and its properties is very important in many of the subjects underlying chemistry (The Orders of Electrons and Chemical Properties, Chemical Bonds, Compounds and Their Formulas, Mixtures). In middle school,
