Standards
1) Develop and use models to illustrate the structure of atoms, including the subatomic particles with their relative positions and charge.
2) Compare and contrast elemental molecules and compound molecules.
3) Classify matter as pure substances or mixtures based on composition.
4) Analyze and interpret chemical reactions to determine if the total number of atoms in the reactants and products support the Law of Conservation of Mass.
5) Use the periodic table as a model to analyze and interpret evidence relating to physical and chemical properties to identify a sample of matter.
6) Create and interpret models of substances whose atoms represent the states of matter with respect to temperature and pressure.
