Chapter 2: Matter

Chemistry is the study of matter - its properties, how we classify and characterize it, and how it changes. Chapter 2 investigates the manner in which chemists describe matter and how one sample of matter can be distinguished from another sample of matter. The Periodic Table of Elements is introduced.
