The study of the arrangement of electrons in atoms and molecules, including orbital theory and molecular orbital theory.

Atomic structure: Understanding the basic structure of atoms and their properties, including electron configurations and ionic states.
Quantum mechanics: Studying the behavior of matter and energy in the atomic and subatomic scale, which is key to understanding electronic structure.
Wave-particle duality: Recognizing that electrons display characteristics of both waves and particles, and how this property influences their behavior in different situations.
Schrödinger equation: Solving this partial differential equation allows us to accurately predict the behavior and properties of electrons in atoms and molecules.
Molecular orbitals: Understanding how the electronic structure of atoms combine to form molecular orbitals in different types of chemical bonds, including covalent, ionic, and metallic bonds.
Electron density and electron distribution: Learning how to use electron density maps and other measurement tools to describe the location of electrons within a molecule, and how this affects its chemical and physical properties.
Spectroscopy: Studying how electromagnetic radiation interacts with matter, including electrons, to provide insights into molecular structure and electronic properties.
Bonding theory: Understanding the different models and theories that explain how atoms bond together to form molecules, including valence bond theory and molecular orbital theory.
Hybridization: Identifying different types of hybridization in molecules and how they influence their electronic structure and reactivity.
VSEPR theory: Recognizing how the shape of a molecule affects its electronic structure and properties, and how to predict molecular geometry using the VSEPR model.
Electronic states: Describing the different electronic states molecules can be in, ranging from the ground state to highly excited states, and how these states affect the molecule's reactivity and spectral properties.
Electronic transitions: Understanding the different types of electronic transitions that molecules can undergo, such as excitation, relaxation, and dissociation, and how these transitions affect the molecule's electronic structure and properties.
Chemical dynamics: Studying how chemical reactions occur on a molecular level and how electronic structure influences reaction pathways and rates.
Computational chemistry: Using computational tools and algorithms to analyze and predict the electronic structure and properties of molecules, including quantum mechanics simulations and molecular dynamics simulations.
Atomic orbitals: These are the regions around an atom where electrons are most likely to be found. They have defined shapes and energy levels.
Molecular orbitals: These are similar to atomic orbitals, but they describe the behavior of electrons in a molecule, rather than an individual atom.
Bonding orbitals: These are molecular orbitals that result from the overlapping of atomic orbitals. Electrons contained within these orbitals contribute to the formation of chemical bonds.
Antibonding orbitals: These are also molecular orbitals that result from the overlapping of atomic orbitals. However, electrons contained within these orbitals result in repulsion and destabilize the molecule.
Hybrid orbitals: These are a combination of atomic orbitals that arise when atoms bond covalently. They have intermediate energies and shapes that allow for optimal overlap in bonding.
Valence shell electron pair repulsion (VSEPR): This theory predicts the spatial arrangement of atoms in a molecule based on the number of electrons in the valence shell and minimizes repulsion between electron pairs.
Lewis structures: These are diagrams that represent the arrangement of atoms in a molecule along with the valence electrons on each atom.
Molecular geometry: This refers to the actual spatial arrangement of atoms in a molecule.
Resonance structures: These are multiple Lewis structures that depict various possible arrangements of electrons in a molecule.
Hybridization: This involves the reorganization of electrons in atomic orbitals to create hybrid orbitals required for bonding.
