Big Idea 2

Chemical and physical properties of materials can be explained by the structure and the arrangement of atoms, ions, or molecules and the forces between them. View Resources (26)

Big Idea 3

Changes in matter involve the rearrangement and/or reorganization of atoms and/or the transfer of electrons. View Resources (48)

Big Idea 4

Rates and chemical reactions are determined by details of the molecular collisions. View Resources (17)

Big Idea 5

The law of thermodynamics describe the essential role of energy and explain and predict the direction of changes in matter. View Resources (32)

Big Idea 6

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. View Resources (34)
