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.
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.
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.
Big Idea 4: Chemical Kinetics
Rates of chemical reactions are determined by details of the molecular collisions.
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.
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.
