What is a Lewis Dot Structure?

Back

A diagram that shows the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule.

Front

What does the Bohr model represent?

Back

The Bohr model represents atoms as having a nucleus surrounded by electrons that travel in circular orbits.
