Front

What is a Lewis structure?

Back

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

Front

What does a single bond represent in a Lewis structure?

Back

A single bond represents the sharing of two electrons between two atoms.

Front

What is the significance of lone pairs in Lewis structures?

Back

Lone pairs represent non-bonding electrons that can affect the shape and reactivity of the molecule.

How do you determine the total number of valence electrons in a molecule?

Back

Add the valence electrons of all atoms in the molecule.

Front

What is the octet rule?

Back

The principle that atoms tend to bond in such a way that they have eight electrons in their valence shell.
