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 ...
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 ...
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]
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)
Electron pair. In chemistry, an electron pair or Lewis pair consists of two electrons that occupy the same molecular orbital but have opposite spins. Gilbert N. Lewis introduced the concepts of both the electron pair and the covalent bond in a landmark paper he published in 1916. [ 1][ 2] MO diagrams depicting covalent (left) and polar covalent ...
Textbooks show students how to manipulate Lewis structures by moving valence electron dots around the chemical structure so each atom has an octet or duet. However, an easier method of teaching Lewis structures for simple molecules, based on the octet rule (the fundamental concept of Lewis structures), enables most students to master drawing ...
Lewis structures are a very important, foundational concept in chemistry. Students usually acquire this knowledge in General Chemistry and need to review it in preparation for Organic Chemistry. However, many students find the task of drawing Lewis structures to be challenging, and not all instructors can budget enough time in class to review ...
Examples of Lewis dot diagrams used to represent electrons in the chemical bonds between atoms, here showing carbon (C), hydrogen (H), and oxygen (O). Lewis diagrams were developed in 1916 by Gilbert N. Lewis to describe chemical bonding and are still widely used today. Each line segment or pair of dots represents a pair of electrons.
