What is a Lewis Structure?

Back

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

Front

What are lone pairs in a Lewis Structure?

Back

Pairs of valence electrons that are not shared with another atom.

Front

What is the significance of valence electrons in bonding?

Back

Valence electrons determine how an atom can bond with other atoms.

Front
