HS-PS1-4 2014
HS-PS1-4: Develop a model to illustrate that the release or absorption of energy from a chemical reaction system depends upon the changes in total bond energy. [Clarification Statement: Emphasis is on the idea that a chemical reaction is a system that affects the energy change. Examples of models could include molecular-level drawings and diagrams of reactions, graphs showing the relative energies of reactants and products, and representations showing energy is conserved.] [ Assessment Boundary: Assessment does not include calculating the total bond energy changes during a chemical reaction from the bond energies of reactants and products.

Enduring Understandings Labs, Investigation, and Student Experiences Essential Questions
1. How do atoms form bonds with one another, and what types of bonds form?
2. How does conservation of mass apply to the interaction of materials in a closed system?
3. The amount of energy required to break a bond is the same that is required to make a bond.
Content Statements
An atom’s electron configuration, particularly of the outermost
Everything is formed from bonds of one atom to the other.
Movement of electrons from one atom to another is the driving force of all natural processes, such as combustion and corrosion.
When materials interact within a closed system, the total mass of the system remains the same.
Understand a Born-Haber diagram.

HS-PS1-4 2014 electrons, determines how the atom interacts with other atoms.
Chemical bonds are the interactions between atoms that hold them together in molecules or between oppositely charged ions.
Rutherford, gold foil experiment,
N. Bohr and Pauli are the major contributors to our understanding of the atomic structure and nature of chemical bonding.
A large number of important reactions involve the transfer of either electrons or hydrogen ions between reacting ions, molecules, or atoms. In other chemical reactions, atoms interact with one another by sharing electrons to create a bond. reactivity of elements and the nature of the chemical bonds
