Introduction:
As we enter our exploration into the field of chemistry, we start to look at the basic properties of matter. By examining the characteristics of different materials and how they interact with other materials, we can begin to understand how early chemists were able to categorize and identify different substances and elements. This unit lays the foundation for our further study of chemistry. |
