Gilbert Newton Lewis described a base as a compound that donates an electron pair. This concept is known as the Lewis acid-base theory, which was proposed in 1923. Lewis also introduced the idea of electron pairs being shared in covalent bonds.

The Lewis structures were introduced by the American chemist Gilbert N. Lewis in 1916. Lewis proposed the concept to represent the bonding between atoms in a molecule using simple symbols and dots to denote valence electrons.
The concept of conjugate acid-base pairs was proposed by G. N. Lewis in 1923. Later, this concept was further developed by G. S. Hammond in 1955, who introduced the idea of considering the relative stability of the conjugate acid-base pairs.
Linus Pauling and Gilbert Lewis are the scientists who described acids as substances that accept electron pairs during the formation of a covalent bond. This concept laid the foundation for the Lewis acid-base theory in chemistry.

The two men who proposed the collision theory are Max Trautx and William Lewis. The theory which was proposed in 1918 explains how chemical reactions occur.
The Lewis structure of an atom gives a clear illustration of the valence electrons.
