# What is the purpose of a Lewis structure? What do the chemical symbol and lines in these structures represent?

May 21, 2017

Evidently, a Lewis structure depicts the structure of a molecule. The chemical symbols are the atoms, and the lines are the bonds, containing two bonding valence electrons.

In other words...

$\text{H"bb( : )"H}$ can be represented by $\text{H"-"H}$

$: \stackrel{. .}{\text{O"bb( : : )stackrel(..)"O}} :$ can be represented by $: \stackrel{. .}{\text{O"=stackrel(..)"O}} :$

$: \text{N"stackrel(bb(. .))( bb( : : ) )"N} :$ can be represented by $: \text{N"-="N} :$

What are the names of these molecules?
