Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.
Plan and conduct an investigation to gather evidence to compare the structure of substances at the macro-scale to infer the strength of electrical forces between particles.
Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction.
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.
Construct an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
