Essential Concepts and Skills / Assignments
The particle theory of matter (PS.2a) & Solids, liquids, gases (PS. 2c)
  • Matter is anything that has mass and occupies space. All matter is made up of small particles called atoms.
  • Be able to differentiate between solids, liquids, and gases using the particle theory.

Pages:60-63
Notes
Elements, Compounds, Mixtures (PS.2b)
  • The atoms of any element are alike but are different from atoms of other elements. Compounds consist of two or more elements that are chemically combined in a fixed ratio. Mixtures also consist of two or more substances, but the substances are not chemically combined.
  • Describe how to determine whether a substance is an element, compound, or mixture.

Physical & Chemical Properties and Characteristics of types of matter based on physical and chemical properties (PS. 2 d, e, f)
  • Matter can be described by its physical properties, which include shape, density, solubility, odor, melting point, boiling point, and color. Some physical properties, such as density, boiling point, and solubility, are characteristic of a specific substance and do not depend on the size of the sample. Characteristic properties can be used to identify unknown substances.
  • Matter can also be described by its chemical properties, which include acidity, basicity, combustibility, and reactivity. A chemical property indicates whether a substance and undergo a chemical change.
  • Distinguish between physical and chemical properties.
  • Determine the identity of an unknown substance by comparing its properties to those of a known substance.
