Fun Facts
*By the age of 3 Gilbert was already reading and many had said he was quite precocious.

*He was home-schooled until he was 14 when he left to go to the University of Nebraska.

Gilbert N. Lewis
Born: 10/25/1875 (West Newton, MA)

Died: 3/23/1946 (Berkeley, CA)

Gilbert lived in both Massachusetts and Germany while coming up with his theories, but lived in California for the end of his life
Gilbert Lewis
Covalent bonding is how 2 atoms come together to create something.
The Lewis Dot Structure are diagrams that show the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule.
In the Lewis theory of acid-base reactions, bases donate pairs of electrons and acids accept pairs of electrons. A Lewis acid is therefore any substance, such as the H+ ion, that can accept a pair of nonbonding electrons. In other words, a Lewis acid is an electron-pair acceptor. A Lewis base is any substance, such as the OH- ion, that can donate a pair of nonbonding electrons. A Lewis base is therefore an electron-pair donor.
Other Scientists
Irving Langmuir- Gilbert showed great interest in Irving's work.

Thomas Lowry-Organic chemist, was involved in the covalent and Valent studies.
