[1] [2] [3] Introduced by Gilbert N. Lewis in his 1916 article The Atom and the Molecule, a Lewis structure can be drawn for any covalently bonded molecule, as well as coordination compounds. [4] Lewis structures extend the concept of the electron dot diagram by adding lines between atoms to represent shared pairs in a chemical bond.
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.
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.
Dot notation may refer to: Newton's notation for differentiation (see also Notation for differentiation) Lewis dot notation also known as Electron dot notation; Dot-decimal notation; Kepatihan notation; Dotted note; DOT language; Dot notation is also used in: Lisp (programming language) Object-oriented programming as syntactic sugar for ...
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.
A key step is drawing the Lewis structure of the molecule (neutral, cationic, anionic): Atom symbols are arranged so that pairs of atoms can be joined by single two-electron bonds as in the molecule (a sort of "skeletal" structure), and the remaining valence electrons are distributed such that sp atoms obtain an octet (duet for hydrogen) with a ...
