Key Concepts

Lewis Structures

Lewis structures are diagrams that represent the valence electrons of atoms in a molecule. They show how the electrons are arranged among the atoms, including bonding pairs of electrons forming covalent bonds and lone pairs of electrons that reside on atoms. These diagrams are essential for predicting molecular geometry, understanding reactivity, and assessing the distribution of electrons in molecules.

Resonance Structures

Resonance structures are multiple valid Lewis structures for a single molecule that differ only in the arrangement of electrons, not the arrangement of atoms. They illustrate the delocalization of electrons within molecules where a single Lewis structure cannot accurately represent the bonding situation. By considering all resonance contributors, one obtains a more complete picture of the electron distribution in the molecule.

Formal Charges

Formal charges are calculated values that help determine the most plausible Lewis structure by indicating the charge distribution within a molecule. They are computed based on the difference between the number of valence electrons in the free atom and the number of electrons assigned to it in the Lewis structure. Minimizing the formal charges across a molecule often correlates with increased stability.

Octet Rule

The octet rule states that atoms tend to bond in such a way that each atom (especially carbon, nitrogen, oxygen, and the halogens) has eight electrons in its valence shell, achieving a noble gas electron configuration. This rule serves as a guideline for constructing Lewis structures, although there are exceptions such as molecules involving elements that can have incomplete octets or expanded octets.
