AP Chemistry Video Tutorials by Big Idea
Big Idea 1: Atoms, Elements and Periodicity
The chemical elements are fundamental building materials of matter, and all matter can be understood in terms of arrangements of atoms. These atoms retain their identity in chemical reactions.
1A: Atoms and the Elements
1B: Electrons
1C: The Periodic Table & Periodicity
1D: Mass Spectrometry and Spectroscopy
1E: Conservation of Atoms
Big Idea 2: Chemical Bonding
Chemical and physical properties of materials can be explained by the structure and arrangement of atoms, ions, or molecules and the forces between them.
2A: States of Matter & Solutions
2B: Intermolecular Forces
2C: Intra Bonding
2D: Bonding and Properties of Solids
Big Idea 3: Chemical Reactions and Energy Changes
Changes in matter involve the rearrangement and/or organization of atoms and/or the transfer of electrons.
3A: Chemical Reactions
3B: Types of Chemical Reactions
3C: Energy Changes
Big Idea 4: Chemical Kinetics
Rates of chemical reactions are determined by details of the molecular collisions.
4A: Factors Affecting Rates
4B: Collision Theory
4C: Reaction Mechanisms
4D: Catalysts
Big Idea 5: Chemical Thermodynamics
The laws of thermodynamics describe the essential role of energy and explain and predict the direction of changes in matter.
5A: Heat, Temperature and Kinetic Energy
5B: Work, Calorimetry and Conservation of Energy
5C: Breaking and Making Chemical Bonds
5D: Physical and Chemical Changing and Bonding
5E: Enthalpy, Entropy and Free Energy
Big Idea 6: Chemical Equilibrium
Any bond or intermolecular attraction that can be formed can be broken. These two processes are in a dynamic competition, sensitive to initial conditions and external perturbations.
