Expressing resonance when drawing Lewis structures may be done either by drawing each of the possible resonance forms and placing double-headed arrows between them or by using dashed lines to represent the partial bonds (although the latter is a good representation of the resonance hybrid which is not, formally speaking, a Lewis structure).
It is named after Warren K. Lewis (1882–1975), [6] [7] who was the first head of the Chemical Engineering Department at MIT. Some workers in the field of combustion assume (incorrectly) that the Lewis number was named for Bernard Lewis (1899–1993), who for many years was a major figure in the field of combustion research.

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.
Physical chemistry is the study of macroscopic and microscopic phenomena in chemical systems in terms of the principles, practices, and concepts of physics such as motion, energy, force, time, thermodynamics, quantum chemistry, statistical mechanics, analytical dynamics and chemical equilibria.
Lewis model may refer to: William Arthur Lewis's model of economic development i.e. the dual-sector model; Richard D. Lewis's Lewis Model of Cross-Cultural Communication; Lewis acids and bases, a model proposed by Gilbert N. Lewis; John Lewis Partnership, a British public limited company owned by a trust on behalf of its employees
A valence bond structure resembles a Lewis structure, but when a molecule cannot be fully represented by a single Lewis structure, multiple valence bond structures are used. Each of these VB structures represents a specific Lewis structure. This combination of valence bond structures is the main point of resonance theory.
Olivia Lewis. ABC/Craig Sjodin Olivia Lewis didn’t find The One while on The Bachelor in 2023 — but that didn’t deter her from putting her heart on the line for season 9 of Bachelor in Paradise.
[14] [15] Lewis's proposal explains the Brønsted–Lowry classification using electronic structure. HA + B ↽ − − ⇀ A − + BH + {\displaystyle {\ce {HA + B <=> A- + BH+}}} In this representation both the base, B, and the conjugate base, A − , are shown carrying a lone pair of electrons and the proton, which is a Lewis acid, is ...
