Lewis structure

A Lewis structure, also known as a Lewis dot structure, is a diagram that depicts the bonding between atoms in a molecule and the lone pairs of electrons that may exist. It was developed by the American chemist Gilbert N. Lewis in 1916. In a Lewis structure: 1. **Atoms** are represented by their chemical symbols (e.g., H for hydrogen, O for oxygen, C for carbon). 2. **Valence electrons** are represented as dots around the atomic symbols.
