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.

The lone pair of electrons in such complexes is available for bonding, however, and therefore the complex itself can act as a Lewis base or ligand. This seen in the ferrocene-related product of the following reaction: SnCl 2 + Fe(η 5-C 5 H 5)(CO) 2 HgCl → Fe(η 5-C 5 H 5)(CO) 2 SnCl 3 + Hg
Melting point (°C) Boiling point (°C) CAS number H 2 S: Hydrogen sulfide is a very toxic and corrosive gas characterised by a typical odour of "rotten egg". −85.7: −60.20: 7783-06-4: CdS: Cadmium sulfide can be used in photocells. 1750: 1306-23-6: Calcium polysulfide ("lime sulfur") is a traditional fungicide in gardening.

A simple Lewis model also does not account for the phenomenon of aromaticity. For instance, Lewis structures do not offer an explanation for why cyclic C 6 H 6 (benzene) experiences special stabilization beyond normal delocalization effects, while C 4 H 4 (cyclobutadiene) actually experiences a special destabilization.
Tin(II) bromide can act as a Lewis acid forming adducts with donor molecules e.g. trimethylamine where it forms NMe 3 ·SnBr 2 and 2NMe 3 ·SnBr 2 [11] It can also act as both donor and acceptor in, for example, the complex F 3 B·SnBr 2 ·NMe 3 where it is a donor to boron trifluoride and an acceptor to trimethylamine.
In chemistry a donor number (DN) is a quantitative measure of Lewis basicity.A donor number is defined as the negative enthalpy value for the 1:1 adduct formation between a Lewis base and the standard Lewis acid SbCl 5 (antimony pentachloride), in dilute solution in the noncoordinating solvent 1,2-dichloroethane with a zero DN.

The first of these quantities is used in atomic physics, the second in chemistry, but both refer to the same basic property of the element. To convert from "value of ionization energy" to the corresponding "value of molar ionization energy", the conversion is: 1 eV = 96.48534 kJ/mol 1 kJ/mol = 0.0103642688 eV [12]
