Lewis Structures

Front

What are Lewis Structures?

Back

Lewis Structures are diagrams that represent the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule.

What is a valence electron?

Back

A valence electron is an electron that is associated with an atom and can participate in the formation of a chemical bond.

Front

Why are valence electrons important in Lewis Structures?

Back

Valence electrons determine how atoms bond with each other and the structure of the molecule.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to bond in such a way that they have eight electrons in their valence shell, achieving a stable electron configuration.

Front

What is a lone pair in Lewis Structures?

Back

A lone pair is a pair of valence electrons that are not shared with another atom and are not involved in bonding.
