Chapter 2: Matter

Chemistry is the study of matter - its properties, how we classify and characterize it, and how it changes. This chapter 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.
